The phrase “av receiver hdmi” shows up in spec sheets for every receiver on the market, but it covers at least four completely different things — and mixing them up is one of the most common reasons a $400 receiver ends up with dropouts, no audio, or a TV that refuses to pass Dolby Atmos through to the speakers. In a 12×16ft living room with a 65-inch TV, a streaming box, and a gaming console all running through the receiver, the difference between HDMI 2.0 and HDMI 2.1 matters the moment you plug in a PS5 or Xbox Series X and try to run 4K/120Hz with HDR — because most entry-level receivers simply can’t pass that signal cleanly.

This guide covers how AV receiver HDMI actually works — ARC vs eARC, passthrough vs switching, HDMI 2.1 bandwidth requirements — and then goes through five receivers currently available on Amazon, each with concrete notes on where their HDMI implementation helps and where it falls short.


> Quick Answer: An AV receiver’s HDMI ports serve two distinct functions: switching (routing video from sources like Blu-ray players or game consoles to your TV) and audio return (pulling audio back from the TV to the receiver via ARC or eARC). For 4K/120Hz gaming passthrough and lossless Atmos audio, you need HDMI 2.1 with eARC. Most receivers under $300 top out at HDMI 2.0b with standard ARC, which limits you to compressed Atmos from streaming apps — not the full lossless object-based audio from a 4K Blu-ray.


What HDMI Actually Does in an AV Receiver (And Why It’s More Complicated Than You’d Expect)

Before getting into individual products, it’s worth understanding the four distinct HDMI roles a receiver plays — because every spec comparison table collapses them into a single line that says “HDMI 2.1” and calls it a day.

1. HDMI Input Switching

This is the most visible function. You plug your sources — game consoles, Blu-ray players, streaming sticks, cable boxes — into the receiver’s HDMI inputs, and the receiver passes the video signal to your TV while extracting and decoding the audio. The receiver acts as the hub, so you only need one HDMI cable running to the TV. The practical issue: if your receiver’s HDMI inputs only support HDMI 2.0, you cannot pass a 4K/120Hz signal from a PS5 to a 4K/120Hz TV. The signal either gets capped at 4K/60Hz or doesn’t display at all.

2. HDMI Passthrough (4K, 8K, HDR)

Passthrough refers to the receiver transmitting the video signal to the TV without processing it — just routing it. A receiver that supports 4K HDR passthrough with HDR10 and Dolby Vision can send that signal to the TV without stripping the HDR metadata. This is separate from what the receiver does with the audio. Many budget receivers support 4K/60Hz passthrough with HDR10 but not 4K/120Hz — which means plugging a current-gen gaming console directly into the TV for video (bypassing the receiver) is often the cleaner solution if the receiver can’t handle 4K/120Hz.

3. HDMI ARC (Audio Return Channel)

ARC uses a single HDMI cable to send audio from the TV back to the receiver — useful when audio originates at the TV (built-in apps, over-the-air broadcasts). The limitation: standard ARC bandwidth maxes out at compressed 5.1 audio (Dolby Digital, DTS). It cannot carry Dolby TrueHD, DTS-HD Master Audio, or uncompressed Dolby Atmos object data. If you’re watching a streaming service through your TV’s built-in apps and want Atmos, you get the compressed Atmos signal — not lossless.

4. eARC (Enhanced Audio Return Channel)

eARC, introduced with HDMI 2.1, has significantly higher bandwidth than ARC and can carry uncompressed audio formats including Dolby TrueHD Atmos and DTS-HD Master Audio. Practically, this means if your TV has eARC and your receiver has eARC, audio from the TV’s built-in apps can reach the receiver as a proper lossless signal — not just a compressed approximation. Both ends of the HDMI cable need to support eARC for this to work. Worth noting: many TVs still negotiate down to standard ARC even when both devices claim eARC support, particularly with generic or non-certified HDMI 2.1 cables. Using a Premium Certified HDMI 2.1 cable (not just any cable rated “2.1”) eliminates most of those negotiation failures.

The Receivers: HDMI Performance in Real Setups

1. Yamaha RX300A — Best Overall HDMI Implementation for a Mixed-Use Living Room

Yamaha RX300A 5.2-Channel AV Receiver

Yamaha RX300A 5.2-Channel AV Receiver

Rating: ⭐ 4.6  |  Price: $399.95

4K/120Hz and eARC support at entry-level pricing makes this the most complete HDMI package in its range — confirmed per manufacturer specs.

Pros:

  • ✅ 4K/120Hz HDMI passthrough (manufacturer-stated)
  • ✅ eARC for lossless Atmos from TV apps
  • ✅ Bluetooth Multipoint for two devices simultaneously
  • ✅ Dolby Atmos and DTS:X decoding
Cons:

  • ❌ No YPAO room correction (auto-cal absent at this tier)
  • ❌ Limited to 5.2 channels — no expansion to 7.1.2 Atmos with height channels
  • ❌ Yamaha app has mixed reliability reviews

Specs: Channels: 5.2 | HDMI: 4 in / 1 out, 4K/120Hz, 8K (manufacturer-stated) | eARC: Yes | Formats: Dolby Atmos, DTS:X | Bluetooth: Multipoint

The Yamaha RX300A is one of the few receivers in this price tier where 4K/120Hz passthrough and eARC are both present — which puts it in a different category than most competitors under $400 that offer one or the other but not both.

In a 12×15ft living room with a PS5 and a 65-inch 4K/120Hz TV connected through the receiver’s HDMI 2.1 input (manufacturer-stated), the RX300A is positioned to pass that signal without forcing you to run a separate HDMI cable directly from the console to the TV. That’s a meaningful practical difference if you want clean cable management and still want the receiver to handle audio decoding from the same source.

The eARC port means Dolby Atmos from Netflix or Disney+ through your TV’s built-in apps can travel back to the receiver as a lossless signal rather than compressed Dolby Digital Plus — assuming you’re using a Premium Certified HDMI 2.1 cable and your TV’s eARC implementation cooperates, which isn’t guaranteed on all TV brands.

Where it falls short: There’s no automatic room correction system on the RX300A. That’s a real gap when you’re setting levels in a room with hardwood floors and parallel walls, where the front left/right balance can easily be off by 2–3dB without a calibration tool catching it. You’re setting channel levels manually with an SPL meter or by ear — workable, but it’s a step that takes time to get right. The 5.2 channel ceiling also means you can’t build a proper 5.1.2 Dolby Atmos Height system with ceiling-mounted speakers without exceeding the receiver’s channel count.

Who this is for: PS5 or Xbox Series X owners in a 12–16ft living room who want 4K/120Hz gaming through the receiver rather than a direct TV connection, and who also stream Atmos content through the TV’s built-in apps. This is the receiver where both use cases work without compromise — at this price tier.

Who should look elsewhere: Anyone planning to add ceiling-mounted height speakers for a 5.1.2 or 7.1.2 Atmos layout should step up to a 7.2-channel receiver. Also, if you rely on auto-calibration to handle a non-symmetrical room or inconsistent speaker placement, the lack of any room correction system here is a genuine limitation — consider the Denon AVR-S570BT or step up to the Denon AVR-X1700H.


2. Denon AVR-S570BT — Reliable eARC and Solid HDMI Switching, With One Key Limitation

Denon AVR-S570BT 5.2-Channel AV Receiver

Denon AVR-S570BT 5.2-Channel AV Receiver

Rating: ⭐ 4.1  |  Price: $449.00

eARC works reliably and Audyssey auto-cal helps with asymmetric rooms, but 4K/60Hz HDMI cap means PS5 gaming runs at half the frame rate potential.

Pros:

  • ✅ eARC for lossless Atmos return channel
  • ✅ Audyssey MultEQ auto-calibration included
  • ✅ 4 HDMI inputs with 8K passthrough (at 30Hz) per manufacturer specs
  • ✅ Bluetooth streaming
Cons:

  • ❌ HDMI maxes at 4K/60Hz for 4K120 gaming sources — significant gap vs newer consoles
  • ❌ Audyssey tends to under-level subwoofers by 2–3dB requiring manual correction
  • ❌ 5.2 channel limit prevents full Atmos height speaker setup

Specs: Channels: 5.2 | HDMI: 4 in / 1 out, 4K/60Hz, 8K/30Hz (manufacturer-stated) | eARC: Yes | Formats: Dolby Atmos, DTS:X | Auto-Cal: Audyssey MultEQ

Check on Amazon →

The Denon AVR-S570BT is a well-documented performer in the under-$500 category, and its HDMI implementation covers most of what a typical 5.1 surround sound setup needs — with one exception that matters more now than it did two years ago.

The eARC port is reliable. Based on user reports, the AVR-S570BT’s eARC handshake with popular TV brands like Samsung, LG, and Sony is more consistent than some competing receivers in this range — which means Dolby TrueHD Atmos from streaming apps on the TV actually reaches the receiver’s decoder rather than falling back to compressed Dolby Digital. That’s the core job of eARC, and the S570BT does it correctly under normal conditions.

The Audyssey MultEQ auto-calibration is a genuine advantage for rooms that aren’t acoustically symmetrical. Running the microphone sweep in a 12×16ft room with furniture along one side and a hard back wall behind the listening position, Audyssey typically catches the front L/R imbalance and adjusts it — though the subwoofer level tends to come out 2–3dB lower than optimal after calibration, which is a well-known Audyssey behavior that requires a manual trim after the fact. It’s a two-minute fix, but one you should expect.

The limitation worth stating plainly: the HDMI inputs on the AVR-S570BT max out at 4K/60Hz for high-frame-rate content, per manufacturer specifications. If you connect a PS5 or Xbox Series X and configure it for 4K/120Hz output, that signal either won’t pass or will be downgraded. The practical workaround — running a separate HDMI cable from the console to the TV for video, and only routing audio through the receiver — defeats part of the reason for having a receiver as a central hub. For a setup that’s primarily Blu-ray, streaming, and 4K/60Hz gaming, this is a non-issue. For anyone running current-gen consoles at full spec, it’s a real constraint.

If you’re building or upgrading a Denon-based system, see the full Denon AVR lineup comparison for context on where the S570BT sits relative to higher-tier models.

Who this is for: A 5.1 or 5.2 home theater setup driven primarily by streaming, Blu-ray, and casual gaming (4K/60Hz or below). The eARC reliability and Audyssey calibration make it one of the more consistent-performing options at this price for audio quality.

Who should look elsewhere: Anyone gaming on PS5 or Xbox Series X at 4K/120Hz, or anyone planning to build a 5.1.2 Dolby Atmos layout with ceiling-mounted height speakers.


3. Sony STR-DH590 — HDMI Switching Works, But No eARC Means Atmos Has a Ceiling

Sony STR-DH590 5.2-Channel AV Receiver

Sony STR-DH590 5.2-Channel AV Receiver

Rating: ⭐ 4.3  |  Price: $498.00

Four HDMI inputs and solid auto-calibration at a budget price point, but standard ARC (no eARC) means Atmos from TV apps arrives compressed, not lossless.

Pros:

  • ✅ 4 HDMI inputs plus 2 outputs — useful for multi-display setups
  • ✅ Auto-calibration (DCAC) included
  • ✅ Dolby Atmos and DTS:X decoding
  • ✅ 4K HDR passthrough with HDR10 and Dolby Vision
Cons:

  • ❌ No eARC — Atmos via TV apps limited to compressed Dolby Digital Plus
  • ❌ HDMI limited to 4K/60Hz passthrough
  • ❌ Older HDMI standard may conflict with newer 8K-capable devices
  • ❌ 5.2 channel maximum

Specs: Channels: 5.2 | HDMI: 4 in / 2 out, 4K/60Hz | eARC: No (ARC only) | Formats: Dolby Atmos, DTS:X | Auto-Cal: DCAC (Digital Cinema Auto Calibration)

Check on Amazon →

The Sony STR-DH590 has been one of the most popular entry-level 5.2-channel receivers on Amazon for years, and it earns that standing through consistent HDMI switching reliability and a usable auto-calibration system — but its HDMI audio return path shows its age in a way that matters for how people actually use their TVs in 2026.

With four HDMI inputs and two outputs, the STR-DH590 is genuinely useful for a dual-display setup — running one output to a TV and a second to a projector screen without additional switching hardware. That’s a practical advantage that most competing receivers in this price range don’t offer. For a 14×16ft basement setup with both a TV and a projector wall, this is the configuration that makes the Sony’s dual HDMI output relevant rather than redundant.

The auto-calibration (Sony’s DCAC — Digital Cinema Auto Calibration) runs in about 5 minutes and handles basic front L/R level matching in a reasonably symmetrical room. In a room with a couch placed 9–10 feet from the front wall and speakers at standard 30-degree toe-in, DCAC typically produces a functional baseline — though like Audyssey, it tends to run the subwoofer level conservatively, and it doesn’t offer the multi-point measurement options found in higher-tier calibration systems.

The critical HDMI limitation: the STR-DH590 uses standard ARC, not eARC. The practical consequence is that Dolby Atmos audio from your TV’s built-in streaming apps (Netflix, Disney+, Apple TV+) arrives at the receiver as compressed Dolby Digital Plus Atmos — not lossless Dolby TrueHD Atmos. If you’re watching content through a streaming device connected directly to the receiver’s HDMI input (Apple TV 4K, Roku Ultra, Fire TV Stick 4K Max), this doesn’t matter, because the audio travels the forward path at full quality. But if you prefer running everything through the TV’s built-in apps, you’re not getting the best audio the receiver can decode. For a budget setup where the priority is 5.1 surround sound rather than lossless Atmos, this is acceptable. For anyone optimizing specifically for the Atmos return channel, it’s a meaningful gap.

For more context on how this fits into a complete 5.1 surround sound build, the best 5.1 surround sound receiver guide covers placement and amp matching in detail.

Who this is for: Budget-conscious buyers setting up a first 5.1 system with a streaming device connected directly to the receiver (bypassing the ARC limitation entirely), or anyone who needs dual HDMI output for a mixed TV-and-projector room.

Who should look elsewhere: Buyers who run all their streaming through the TV’s built-in apps and want lossless Atmos returned to the receiver. Also, current-gen gamers — this receiver’s 4K/60Hz HDMI cap is the same constraint as the S570BT.


4. Pyle 9.1-Channel AV Receiver — The HDMI 2.1 Claim Needs Verification Before You Buy

Pyle 9.1-Channel AV Receiver

Pyle 9.1-Channel AV Receiver

Rating: ⭐ 4.1  |  Price: $249.99

9.1 channels and HDMI 2.1 stated on spec sheet, but real-world HDMI compatibility and power-per-channel figures need independent verification before a critical install.

Pros:

  • ✅ 9.1 channel configuration — supports larger speaker layouts than most competitors at this price
  • ✅ HDMI 2.1 listed in product specs
  • ✅ Subwoofer output included
  • ✅ Bluetooth streaming
Cons:

  • ❌ Power per channel not independently verified — manufacturer-stated figures should be treated with caution
  • ❌ HDMI 2.1 compatibility with specific TV brands unconfirmed in user reports
  • ❌ Build quality inconsistencies reported in user reviews
  • ❌ Limited firmware support history compared to Denon or Yamaha

Specs: Channels: 9.1 | HDMI: 2.1 (manufacturer-stated) | Subwoofer Output: Yes | Bluetooth: Yes | Formats: Dolby Digital, DTS (lossless Atmos support unconfirmed)

Check on Amazon →

The Pyle 9.1-channel receiver is priced in a range where most manufacturers can only offer 5.2 channels with HDMI 2.1 support, which makes the channel count and the HDMI 2.1 listing look compelling on paper. The reality is more nuanced.

Pyle lists HDMI 2.1 on this product’s spec sheet, and that’s the figure used here — per the fact-first policy, it’s labeled manufacturer-stated. What’s absent from the publicly available data is independent confirmation of whether that HDMI 2.1 implementation supports the full 48Gbps bandwidth needed for 4K/120Hz with HDR, or whether it uses a narrower HDMI 2.1 implementation that caps out at lower throughput. HDMI 2.1 is a specification range, not a single performance tier — a device can technically qualify as HDMI 2.1 while only supporting a subset of the spec’s bandwidth capabilities. For a receiver at this price point handling 9.1 channels simultaneously, the internal processing demands are high, and that’s a configuration worth verifying before committing to a whole-room installation.

The 9.1-channel layout itself is genuinely useful in the right room. A 14×18ft dedicated media room with ceiling-mounted Atmos height speakers in a 7.1.2 or 5.1.4 configuration is where nine amplifier channels actually get used. In a standard 12×14ft living room, a 9.1 receiver is more channels than most installations can use effectively, and the additional amplifier stages running idle produce some heat without acoustic benefit.

User reports on Amazon for this model include mixed notes on HDMI handshake reliability with certain TV brands, and the power output claims (which Pyle doesn’t publish with standard independent measurement methodology) should be treated with caution. The watts-per-channel figure at 9.1 channels driven simultaneously will be significantly lower than the peak single-channel figure often highlighted in marketing.

Who this is for: Anyone building a larger-room 9.1 layout on a tight budget where the channel count is the primary driver and they can verify HDMI compatibility with their specific TV model before purchasing.

Who should look elsewhere: Buyers prioritizing HDMI reliability, lossless Atmos passthrough verification, or consistent firmware support. For a more reliable 5.1 or 5.2 foundation, the Denon AVR-S570BT or Yamaha RX300A offer a better-documented performance baseline.


5. Pyle 5.2-Channel Hi-Fi Home Theater Receiver — Basic HDMI Switching on a Tight Budget

Pyle 5.2-Channel Hi-Fi Home Theater Receiver

Pyle 5.2-Channel Hi-Fi Home Theater Receiver

Rating: ⭐ 4.1  |  Price: $190.49

Budget entry point for HDMI switching in a 5.2 setup, but HDR passthrough capability and eARC support are unconfirmed — verify compatibility with your TV before purchasing.

Pros:

  • ✅ 5.2 channel layout covers standard home theater configurations
  • ✅ Bluetooth included
  • ✅ USB and DAC inputs for flexible source connectivity
  • ✅ Low entry price for HDMI-equipped 5.2 receiver
Cons:

  • ❌ HDMI version and 4K HDR passthrough specifications not independently confirmed
  • ❌ eARC support unconfirmed — likely standard ARC or no ARC at this price
  • ❌ 1000W MAX power rating is a peak figure
  • ❌ not a continuous RMS measurement — real per-channel output will be significantly lower
  • ❌ Limited post-purchase support documentation

Specs: Channels: 5.2 | HDMI: 4K support (manufacturer-stated) | Bluetooth: Yes | USB: Yes | DAC: Yes | Max Power: 1000W (peak, not RMS)

Check on Amazon →

The Pyle 5.2-channel receiver is the lowest-priced option in this group, and the HDMI support listed in its product description follows the same pattern as the 9.1-channel model — manufacturer-stated 4K support without detailed HDMI version confirmation in independently verifiable documentation.

The 1000W MAX power figure prominently featured in the product listing is a peak measurement, not a continuous RMS figure measured at a specific ohm load. A receiver driving five channels simultaneously at a realistic impedance (6–8 ohms) produces a per-channel continuous output that is substantially lower than the peak headline number. For a casual 5.1 setup with speakers rated for modest power handling — typical bookshelf speakers in the 50–100W range — this isn’t necessarily a dealbreaker, but understanding what that number means prevents mismatched expectations.

At this price, the Pyle 5.2 receiver fills a specific gap: someone who needs basic HDMI switching for a 5.2 layout, has existing speakers with reasonable sensitivity ratings (88dB/W/m or higher), and doesn’t require auto-calibration, Audyssey, or eARC for their specific use case. In a 10×12ft bedroom setup with compact bookshelf speakers and a single source device, basic HDMI routing and 5.2-channel decoding from a streaming device is achievable — but the HDMI limitations mean verifying compatibility with your TV’s specific HDMI ARC port configuration before purchasing.

Who this is for: A strict-budget first step into a 5.2 system, understanding the limitations. Works best with a streaming device connected directly to the HDMI input (not relying on ARC return), and with speakers that don’t require high amplifier drive current (6-ohm or lower impedance speakers are a risk at this price tier without confirmed impedance handling specs).

Who should look elsewhere: Anyone who needs confirmed 4K HDR passthrough, eARC, auto-calibration, or reliable firmware support. The $50–$100 price difference up to the best budget AV receiver tier gets you verified specifications and a much better-documented performance baseline.


HDMI Setup: Connecting Your AV Receiver Correctly

Understanding which cable goes where prevents the most common HDMI issues.

The Standard Hub Configuration

Connect each source device (game console, Blu-ray player, Apple TV, streaming stick) to the receiver’s numbered HDMI inputs. Run a single HDMI cable from the receiver’s HDMI OUT (or MONITOR OUT) to the TV’s HDMI ARC or eARC port. This one cable handles both the video signal going to the TV and the audio return channel coming back from the TV to the receiver.

For eARC to function, this single cable between receiver and TV must be a Premium High Speed HDMI Cable certified for HDMI 2.1 bandwidth (48Gbps). Using a standard “high speed” HDMI cable — even a quality one — can prevent eARC negotiation and fall back to standard ARC, stripping lossless audio formats in the process.

4K/120Hz Gaming: Direct TV Connection vs. Receiver Routing

If your receiver’s HDMI inputs are capped at 4K/60Hz (as with the Denon AVR-S570BT and Sony STR-DH590), you have two options for a PS5 or Xbox Series X:

  1. Connect the console directly to the TV’s HDMI 2.1 port for 4K/120Hz video. Run a separate optical or HDMI ARC connection for audio. Audio quality is limited to what ARC or optical can carry (compressed formats).
  2. Connect the console to the TV via HDMI 2.1, and use the TV’s eARC port to send audio back to the receiver. This works cleanly if the receiver supports eARC — audio decoding stays in the receiver’s hands while the TV handles the high-frame-rate video path directly.

Neither option is ideal. The cleanest solution is a receiver with confirmed HDMI 2.1 inputs that can handle 4K/120Hz through the hub — which is what positions the Yamaha RX300A as the more complete HDMI solution in this price range for gaming setups.

Impedance Matching: What HDMI Doesn’t Tell You

One thing HDMI specs don’t address is speaker impedance compatibility. If you’re connecting 4-ohm or 6-ohm speakers to a receiver rated for 8-ohm minimum loads, the receiver’s protection circuit may trigger under sustained high-volume loads — regardless of how good the HDMI passthrough is. Check your receiver’s minimum impedance rating against your speaker specs before finalizing the setup. For more on building out a complete system, the AV receivers for home theater guide covers impedance matching and channel configuration in depth.


Frequently Asked Questions

How do I connect my TV to an AV receiver with HDMI?

Connect the receiver’s HDMI OUT (labeled “MONITOR OUT” on most units) to your TV’s HDMI ARC or eARC port using a single HDMI cable. Then connect each source device — streaming sticks, Blu-ray players, game consoles — to the receiver’s numbered HDMI inputs. The receiver routes video to the TV and decodes audio from both sources and the TV’s ARC/eARC return channel. Use a Premium Certified HDMI 2.1 cable for the receiver-to-TV connection if eARC is involved.

What is the HDMI port on an AV receiver used for?

AV receiver HDMI ports serve two functions: input switching (routing video from multiple source devices to your TV) and audio return (receiving audio back from the TV via ARC or eARC). The input ports accept source signals; the output port sends video to the TV and simultaneously handles audio return. eARC-capable output ports can receive lossless Dolby TrueHD Atmos and DTS-HD Master Audio from the TV — standard ARC ports are limited to compressed 5.1 formats.

Is it better to run HDMI through the receiver or directly to the TV?

For audio quality, routing HDMI through the receiver is better — the receiver’s internal decoders process Dolby Atmos, DTS:X, and lossless audio formats more accurately than a TV’s built-in speakers or compressed audio output. For 4K/120Hz gaming, it depends on whether your receiver supports HDMI 2.1: if not, connecting the gaming console directly to the TV for video (then using eARC to return audio to the receiver) avoids frame-rate downsampling while keeping audio decoding in the receiver.

Is HDMI to RCA the same as HDMI AV?

No. HDMI carries digital audio and video signals; RCA carries analog audio (and composite analog video on the yellow RCA jack). An HDMI-to-RCA adapter must perform digital-to-analog conversion and cannot carry surround sound formats — it’s limited to stereo analog output. This is a completely different signal path from HDMI ARC or eARC, which are digital audio return channels on a standard HDMI cable. Using an HDMI-to-RCA converter to connect a modern AV receiver to an old TV eliminates all surround sound decoding capability.

What’s the difference between HDMI ARC and eARC on an AV receiver?

Standard ARC has limited bandwidth and carries only compressed audio formats — Dolby Digital 5.1, DTS 5.1, and compressed Dolby Atmos (Dolby Digital Plus). eARC, part of the HDMI 2.1 specification, has substantially higher bandwidth and supports uncompressed formats including Dolby TrueHD Atmos and DTS-HD Master Audio. If your TV’s built-in apps are your primary audio source, eARC is the only way to get lossless audio from those apps to your receiver. Both the TV and the receiver must support eARC, and the connecting cable must be a Premium Certified High Speed HDMI cable.

Does HDMI version matter when choosing an AV receiver?

Yes, significantly. HDMI 2.0 (or 2.0b) receivers support 4K/60Hz passthrough with HDR10, Dolby Vision, and HLG — adequate for most streaming and Blu-ray content. HDMI 2.1 receivers add 4K/120Hz and 8K/30Hz passthrough with Variable Refresh Rate (VRR) and Auto Low Latency Mode (ALLM) — which directly affects gaming performance with PS5, Xbox Series X, and PC. If you’re not gaming on a current-gen console, HDMI 2.0b is sufficient. If you are, HDMI 2.1 inputs on the receiver are worth prioritizing.

How many HDMI inputs do I need on an AV receiver?

Count your source devices and add one as a buffer. A typical living room setup with a streaming device, a gaming console, and a Blu-ray player needs a minimum of three HDMI inputs — most receivers in this category offer four, which is generally enough. If you’re also connecting a cable box or a second gaming console, look for five or more inputs. The Sony STR-DH590 and the Denon AVR-S570BT both offer four inputs, which covers most setups without requiring an external HDMI switch.

What causes audio dropout when using HDMI ARC on an AV receiver?

The three most common causes are: (1) using a standard HDMI cable rather than a Premium High Speed HDMI 2.1-certified cable between the receiver and TV — the bandwidth difference causes intermittent handshake failures; (2) TV firmware updates that change how the ARC/eARC port negotiates with the receiver, often requiring the receiver’s HDMI control (CEC) settings to be disabled and re-enabled; and (3) mismatched ARC vs eARC settings — if the TV is set to eARC output but the receiver only supports standard ARC, the negotiation may fall back to no audio rather than a clean ARC connection. Swapping to a confirmed Premium Certified cable resolves the first issue in most cases.


Building a Complete HDMI-Connected Home Theater System

HDMI capability is only one axis of a receiver decision. Channel count, impedance compatibility, and auto-calibration quality all interact with HDMI to determine how a system actually performs in a specific room.

For most 12×16ft living rooms with a 5.1 or 5.2 speaker layout, the Denon AVR-S570BT covers the audio quality fundamentals — eARC, Audyssey calibration, and four HDMI inputs — while the Yamaha RX300A adds 4K/120Hz gaming capability at a comparable price. The Sony STR-DH590 is the better call for dual-display setups or for anyone whose priority is a reliable, well-documented receiver with a strong track record and a sub-$500 price. The Pyle options serve a specific budget niche but carry more uncertainty on HDMI compatibility than the Denon, Yamaha, or Sony alternatives.
