Sony TV ARC / eARC Not Working: How to Fix

Sony TV ARC or eARC not working usually means your TV can’t negotiate audio with the soundbar or receiver, so you get no sound, dropouts, or the wrong output. The most common causes are HDMI ARC/eARC not enabled, incompatible HDMI ports/cables, or incorrect audio settings on one device. Use the troubleshooting steps below to pinpoint the exact setting to change and restore reliable audio.

If Sony TV ARC/eARC isn’t working, the fastest fix is to confirm you’re using the correct HDMI port and that both devices have matching ARC/eARC settings enabled. Then power-cycle everything and re-test with a known-good HDMI cable. This article walks you through the exact checks that usually restore audio for soundbars and AV receivers.

This is for people trying to get audio from a Sony TV to a soundbar or receiver via ARC/eARC, especially when the TV shows “no audio,” the sound outputs to the TV speakers, or HDMI audio handshaking keeps failing.

Check the HDMI port + cable (most common cause)

When ARC/eARC fails, the most direct cause is almost always the HDMI connection—wrong port or a cable that doesn’t fully support ARC/eARC behavior. If you correct the port selection first, you often avoid hours of “format tweaking.”

– Make sure you plug into the Sony HDMI port labeled ARC (or eARC on supported models), not a random HDMI input. On many Sony TVs, only one HDMI input is wired to return audio.

– Use a proper HDMI cable that supports ARC/eARC; if you have one, swap in a different HDMI cable to rule out a bad lead. In my experience walking people through this, “it almost works” is common with cables that are marginal for the HDMI handshake.

– If you’re using an older AVR/soundbar, confirm it actually supports eARC vs ARC (they’re not the same). If the receiver/soundbar only supports ARC, forcing eARC-related settings can prevent a clean handshake.

Match ARC/eARC settings on both devices

Most ARC/eARC “no audio” problems are caused by mismatched settings—one device expects ARC while the other is effectively listening for eARC. The quickest path is to verify the audio return channel is enabled on both sides and that the TV is routing audio externally instead of to TV speakers.

– On the Sony TV, enable the ARC/eARC audio setting (the wording varies by model—look for HDMI/Audio Return Channel or eARC).

– On the soundbar/receiver, enable ARC or eARC in its own settings—many failures happen because only one side is enabled.

– If there’s an option for Digital Audio Output / HDMI audio, set it so it allows the external audio path (and not TV speakers).

To make that distinction easier, here’s a practical ARC vs eARC comparison you can use while you’re in menus:

Feature	ARC	eARC
HDMI audio return bandwidth	Up to ~1 Mbps	Up to ~37 Mbps
Typical advanced format support	More limited; often relies on lossy streaming-friendly codecs	Better support for high-bandwidth “next-gen” formats
Handshake resilience	Can be more sensitive to device/CEC timing	Designed to improve reliability
Recommended setup	OK for basic soundbar use and older AVRs	Best when you want consistent high-quality bitstreams
Best for gaming consoles routed through the TV	Works, but fewer format “escape hatches”	Usually fewer handshake surprises
When formats fail	May fall back or result in “no audio” depending on TV/device behavior	More likely to keep the intended bitstream path
eARC-only format delivery	Not suitable for “HD” audio bitstreams	Designed to carry them
Common symptoms when misconfigured	TV speakers stay on, soundbar mute, “no audio” prompts	Same symptoms, but often after menu changes or input switches
Menu complexity	Usually simpler	More knobs (eARC mode, audio return behavior)
Best For	ARC-compatible soundbars and “standard” surround setups	Higher-end audio needs where you want reliable advanced-format delivery

Power-cycle and re-handshake (resets the connection)

If ARC/eARC handshaking is stuck, a full power-cycle is often the fastest reset. This forces the TV and the soundbar/receiver to renegotiate the HDMI audio return channel state cleanly.

– Turn off the TV and the external audio device, then unplug both from power for 30–60 seconds.

– Start the setup in this order: external audio device first, then the Sony TV—then test audio again.

– If it improves briefly but fails later, keep reading—handshaking issues often trace back to cable/HDMI-CEC or mismatched formats.

One reason this works is that HDMI-CEC (Consumer Electronics Control) and ARC/eARC setup are part of the HDMI “handshake” process. If either device caches an incomplete state from a previous boot, the next restart can keep repeating the failure until you clear it via a true power removal.

Verify audio format and HDMI-CEC behavior

When your hardware wiring is correct but the TV still won’t send audio, the culprit is usually audio format selection or HDMI-CEC behavior. Adjusting output format (especially Auto vs a PCM-friendly mode) and temporarily managing CEC gives you a clean test path.

– Change the TV’s audio output format (e.g., switch between Auto and a PCM-friendly option) to see whether the audio handshake is choking on an unsupported codec. This is especially relevant when you’re trying to pass advanced formats.

– Check HDMI-CEC/BRAVIA Sync settings on the TV and the soundbar/receiver; disable it temporarily to test, then re-enable once audio is stable.

– If you see eARC-related symptoms only with one input (like a specific streaming app or console), test that same HDMI source after fixing the settings above. Per-input audio routing settings can differ even on the same Sony TV.

A quick technical anchor: ARC and eARC exist partly because they carry different “audio bandwidth budgets.” According to HDMI.org, eARC supports up to ~37 Mbps for audio return, while ARC is limited to around ~1 Mbps. According to Dolby, Dolby TrueHD is capable of lossless bitrates up to ~18 Mbps—so if your chain can’t carry that payload, you can see “no audio” or forced fallbacks. And ARC itself was introduced with HDMI 1.4 (widely deployed beginning in 2009), which means many older systems are still on the smaller ARC pathway rather than eARC.

What can go wrong (and how to avoid wasted time)

Even when you follow the steps, ARC/eARC is sensitive to a few setup mistakes. If you recognize these patterns early, you can avoid “fixing” the wrong setting while the real issue stays in place.

– Wrong HDMI input: plugging into a non-ARC/eARC port is the quickest way to get “no audio” or speaker output staying on the TV.

– Mismatch: ARC vs eARC: enabling eARC on one device when the other only supports ARC can break the handshake.

– Bad cable timing: some HDMI cables “almost work” but fail intermittently—swapping cables is often faster than changing settings endlessly.

– TV output stuck to internal speakers: if the audio route never changes after you connect, re-check the TV’s audio output selection and enabled HDMI audio return option.

– Edge case with specific devices: some receivers/soundbars behave differently depending on whether the TV is controlling them via CEC—test with HDMI-CEC off if you suspect that.

As of 2026, many Sony models still rely on BRAVIA Sync/HDMI-CEC to coordinate device behavior, so the “it works after reboot but not after hours” symptom usually points back to CEC timing plus audio format negotiation.

Verdict / tip (what’s worth doing first)

Start with the HDMI port + cable + matching settings on both devices, then do a full power-cycle to force a clean ARC/eARC re-handshake. If audio still won’t pass, try adjusting audio format and temporarily changing HDMI-CEC behavior to isolate the cause.

Skip the deeper troubleshooting (like extensive format/CEC tinkering) if you’re on a basic setup with only TV speakers or if your external device doesn’t support ARC/eARC in the first place—those won’t be solved by settings alone.

Quick scan checklist (save this)

– [ ] HDMI cable supports ARC/eARC (swap cable to test)

– [ ] Connected to ARC/eARC-labeled Sony HDMI port

– [ ] TV ARC/eARC setting enabled

– [ ] Soundbar/receiver ARC/eARC enabled

– [ ] TV audio output route set for external speakers

– [ ] Power-cycle TV + audio device, reconnect and test again

– [ ] If still failing: test audio format (Auto vs PCM-friendly) + HDMI-CEC off/on

Frequently Asked Questions

Why isn’t ARC or eARC working on my Sony TV, and how can I tell if it’s the connection or the settings?

ARC/eARC issues are usually caused by an incorrect HDMI port, missing CEC/BRAVIA Sync settings, or a faulty HDMI cable. First, confirm you’re using the HDMI port labeled ARC or eARC on the Sony TV and that your soundbar/receiver is connected to the corresponding HDMI input. Then check that BRAVIA Sync (HDMI-CEC) is enabled and that audio output is set to Audio System. If ARC works but eARC doesn’t, it can also be a bandwidth/codecs limitation or an eARC handshake issue between devices.

How do I enable Sony BRAVIA Sync so ARC/eARC audio works with my soundbar or AV receiver?

On your Sony TV, go to Settings → Watching TV / Channels (or Sound settings depending on model) → External Inputs → BRAVIA Sync settings and enable Control for HDMI. Make sure HDMI-CEC is turned on for both the TV and the connected receiver/soundbar (if the device supports it). After enabling, set TV speakers/audio output to Audio System and restart both the TV and audio device to force a fresh ARC/eARC handshake.

Which HDMI cable and port should I use for Sony ARC vs eARC to avoid “no sound” or dropouts?

For ARC, a standard High-Speed HDMI cable is often sufficient, but using a newer Premium High Speed (or better) HDMI cable helps avoid handshake problems. For eARC, use an HDMI cable that supports eARC/HDMI 2.1 capabilities and connect it to the TV port specifically labeled eARC (not a regular HDMI port). Also ensure your receiver/soundbar HDMI input is set correctly (often labeled “TV ARC” or “eARC”) to prevent the TV from sending audio to the wrong endpoint.

What should I do if I’m getting sound delay, lip-sync issues, or audio cutting out with Sony eARC/ARC?

Start by setting your audio output format to a compatible option on the TV (commonly “Auto” or “PCM” as a troubleshooting step). If lip-sync is off, disable any conflicting audio processing on the receiver/soundbar (like extra “surround” or “game” modes) and confirm the TV’s Audio Delay/Lip Sync settings are aligned. After changes, power-cycle the TV and audio device and re-check the HDMI-CEC/BRAVIA Sync status so ARC/eARC stays stable.

Best troubleshooting steps: how can I fix Sony TV ARC/eARC not working when my TV menu shows no Audio System or can’t detect my receiver?

Update the TV firmware and, if available, update your soundbar/AV receiver firmware to ensure HDMI-CEC and eARC compatibility. Then reset HDMI settings by disabling and re-enabling BRAVIA Sync/Control for HDMI, and try a different HDMI port labeled ARC/eARC on the Sony TV. Finally, try the connection with another HDMI cable and test with a different source device to confirm whether the issue is ARC/eARC negotiation or a problem with a specific HDMI input.
