When your Sony TV is connected to a soundbar and you get complete silence, it is understandably frustrating. This usually comes down to an audio output setting, a muted or incorrect volume level on the TV or soundbar, or a connection/configuration issue with HDMI ARC/eARC or optical. Below are calm, fast steps to identify the cause and restore sound.
Sony TV no sound from a soundbar is usually caused by the TV audio output being set to the wrong option (or the soundbar/connection type not matching). Start by changing the TV’s Sound Output to your soundbar (HDMI ARC/eARC or Optical), then reboot both devices and re-check the cable/port. If sound still won’t come through, inspect the soundbar’s input mode and run through the TV’s audio format settings.
In most cases, this guide applies to people with a Sony Bravia TV who can hear audio from streaming apps or other devices, but the TV’s own audio won’t route through the connected soundbar. The issue is rarely “your soundbar is broken” and more often a routing mismatch between Sony Bravia’s audio output and the soundbar’s selected input.
Check the Sony TV Sound Output (most common fix)
The fastest answer is to set your Sony Bravia TV’s Sound Output to the exact connection type you’re using—HDMI ARC/eARC for HDMI, or Optical/Audio System for TOSLINK. If the TV is still outputting to internal speakers (or to the wrong external path), the soundbar will receive silence even though everything looks connected.
The Sony Bravia menu wording varies by model, but the flow is consistent:
– Open your Sony TV’s audio settings and set Sound Output to the correct connection (commonly Audio System).
– If you see multiple output choices (for example, separate options for HDMI ARC, eARC, or Optical), match the one that corresponds to your soundbar’s wiring.
– After switching, test a built-in Sony Bravia app (streaming is easiest) to confirm the audio routing changed.
Most Common Sony Bravia → Soundbar “No Sound” Routing Mistakes (2026)
| # | Sony Bravia setting mismatch | Connection type | Typical symptom | Ease of first-fix |
|---|---|---|---|---|
| 1 | Sound Output left on TV Speakers instead of Audio System/ARC/Optical | HDMI ARC or Optical | Soundbar receives no TV audio | ★★★★★ |
| 2 | Sound Output set to the wrong external route (ARC vs Optical) | HDMI ARC vs Optical | Only one connection “works” (apps OK, TV audio silent) | ★★★★☆ |
| 3 | ARC enabled, but soundbar connected to a non-ARC HDMI port | HDMI (wrong port) | No audio from TV even though HDMI picture works | ★★★★☆ |
| 4 | eARC mismatch (TV set for eARC, soundbar expects ARC—or vice versa) | HDMI ARC/eARC | Intermittent silence after switching inputs | ★★★☆☆ |
| 5 | Digital Audio Output format set to a mode the soundbar can’t decode | ARC or Optical | Soundbar stays muted (no “signal detected”) | ★★☆☆☆ |
| 6 | TV set to PCM-only, but soundbar expects bitstream (or vice versa) | ARC or Optical | No sound on TV audio; other sources may still play | ★★★☆☆ |
| 7 | HDMI handshake disruption after updates (ARC/eARC resync needed) | HDMI ARC/eARC | Works briefly, then drops back to silence | ★★★☆☆ |
Before you move on: the “Sound Output” step is usually the shortest path to fix Sony Bravia TV no sound from soundbar because it changes the audio routing destination in one menu adjustment.
Power cycle and re-seat the connection
The quickest way to clear most Sony Bravia audio routing glitches is to power cycle both the TV and the soundbar, then reconnect the cable firmly. This forces ARC/eARC or optical (TOSLINK) to re-negotiate the audio path—often fixing silence caused by a stale handshake.
Do this sequence:
– Turn off the Sony Bravia TV and the soundbar.
– Unplug both devices for (use the exact time your manual recommends).
– Reconnect the cable securely:
– If you’re using HDMI ARC/eARC, verify you’re in the TV’s ARC/eARC-designated HDMI port (not any random HDMI input).
– If you’re using Optical, re-seat the TOSLINK connector so it clicks fully.
– Power the Sony Bravia TV back on first, then the soundbar, and test a built-in app again.
From a practical troubleshooting perspective, this step helps because ARC/eARC requires two devices to agree on audio capabilities. If either device is still “remembering” the previous state, the Sony Bravia TV may keep sending audio to a sink the soundbar isn’t listening for.
Verify the soundbar input mode
The fastest answer here is simple: set the soundbar to the same input that matches how the Sony Bravia TV is physically connected. Even with a perfect Sony Bravia “Sound Output” setting, the soundbar can stay silent if it’s listening on the wrong source.
Check the soundbar’s input selection:
– If you connected via HDMI ARC/eARC, ensure the soundbar input is HDMI ARC (or ARC).
– If you connected via Optical, switch the soundbar input to OPTICAL or TV (naming differs by model).
– If the soundbar supports “Auto” input switching, it may still lock onto the wrong source—switch manually and retry.
– Look for a signal indicator on the soundbar display:
– Many models show a brief message when ARC/optical audio starts (e.g., “ARC,” “TV,” or a codec label).
If your setup is “Sony Bravia TV → soundbar,” remember that the TV doesn’t control what the soundbar is listening for. The Sony Bravia TV can send audio all day, but the soundbar must be set to the matching input.
Match HDMI ARC/eARC settings (if you’re using HDMI)
If you’re using HDMI, the best fix is to confirm ARC/eARC is enabled on the Sony Bravia TV and that the soundbar is connected to the TV’s ARC/eARC HDMI port. ARC (Audio Return Channel) sends audio back to the soundbar over HDMI, while eARC improves bandwidth and format handling.
Use these targeted checks on your Sony Bravia TV:
– Enable HDMI ARC or eARC (Sony’s wording varies by model and year).
– Confirm the HDMI cable is connected to the TV’s ARC/eARC port (often labeled with “ARC” on the TV’s input panel).
– If your soundbar supports eARC but the Sony Bravia TV is only set for ARC (or vice versa), audio can drop—try toggling ARC/eARC and re-test.
A few technical anchoring points help explain why this matters:
– ARC is part of HDMI 1.4 (announced in 2009) HDMI Licensing Administrator.
– eARC is part of HDMI 2.1 (introduced alongside HDMI 2.1 capability) HDMI.org.
– eARC substantially increases audio return bandwidth (often cited as up to ~37 Mbps vs ARC’s ~1 Mbps) HDMI.org.
As of 2025–2026, many Sony Bravia models ship with both ARC and eARC-related toggles, so “it has HDMI” is not the same as “it’s configured for audio return.”
If you’re using Optical (TOSLINK): confirm the right format
If you’re using Optical, the quickest fix is to set the Sony Bravia TV output to Optical/Audio System and align the soundbar input to OPTICAL. Optical (TOSLINK) typically carries compressed audio reliably, but it can break when the TV outputs a format the soundbar can’t decode.
Do this checklist:
– Switch Sony Bravia Sound Output to Optical/Audio System.
– Set the soundbar input to OPTICAL (or the TV/Optical source).
– Review Digital Audio Output settings on the Sony Bravia TV:
– If you see options such as PCM vs Bitstream/Auto, try PCM (for compatibility) or Bitstream (for surround) depending on what your soundbar supports.
– Temporarily ensure the TV’s internal speakers are OFF during testing, so you don’t get confusing “no audio” behavior from competing audio paths.
Why this works: Optical is often less forgiving when the TV’s selected codec (compression format) doesn’t match what the soundbar expects. Sony Bravia TV audio menus make this easy to fix once you confirm you’re actually outputting through the Optical path.
What can go wrong (and how to avoid it)
Most “Sony TV no sound from soundbar” situations happen because one side of the chain is configured correctly while the other side is not. The fastest prevention is to treat Sony Bravia TV settings and soundbar input modes as a matched pair, not independent choices.
Common failure points to watch for:
– Leaving Sony Bravia on internal speakers or selecting the wrong output destination (soundbar never receives audio).
– Using the TV’s non-ARC HDMI port, even though ARC is enabled (ARC audio won’t return over a standard HDMI input).
– Selecting the wrong soundbar input mode (HDMI vs Optical vs Bluetooth/TV).
– HDMI handshake problems after updates:
– ARC/eARC negotiation can occasionally break after firmware changes; power cycling usually helps.
– After any major Sony Bravia update, re-check that ARC/eARC is still enabled.
– Using an AVR, HDMI switch, or soundbar adapter:
– These can change the audio path and sometimes block ARC/eARC behavior.
– If you can, temporarily connect Sony Bravia directly to the soundbar to isolate the fault.
To clarify the connection trade-offs, here’s a quick comparison of the “routing reliability” you’ll typically see with Sony Bravia setups:
| Connection | Pros (Sony Bravia → soundbar) | Cons / common “no sound” trigger |
|---|---|---|
| HDMI ARC/eARC | Single-cable audio return; better support for modern surround formats (especially eARC) | Port labeling matters (ARC/eARC port only); handshake can fail after updates |
| Optical (TOSLINK) | Simple, stable for many soundbars; independent of HDMI ARC/eARC behavior | Codec/format mismatch (PCM vs bitstream) can cause silence |
| Bluetooth (if used) | Easy pairing; no HDMI/optical routing complexity | TV audio routing menus may not apply; “wrong route” can look like TV no-audio |
If you want to avoid back-and-forth, pick one connection type (HDMI ARC/eARC or Optical) for testing with your Sony Bravia TV and keep the others disconnected during diagnosis.
Verdict: what to try first (and who should skip advanced tweaking)
Start with Sony Bravia TV Sound Output selection + the correct HDMI ARC/eARC or Optical port pairing, then do a power cycle and verify the soundbar’s input mode. This resolves the majority of Sony TV no sound from soundbar cases with minimal risk because it fixes the core “audio routing” failure, not just the symptoms.
There are downsides to deeper audio-format tweaking:
– Changing TV “Digital Audio Output” options can lead to new silence if the soundbar expects a different codec/bitstream mode.
– If you rely on eARC for advanced formats, toggling between ARC/eARC may temporarily disrupt audio until devices re-negotiate.
Skip advanced tweaking (format-level changes) if:
– You’re not comfortable modifying Sony Bravia audio codec settings.
– Your soundbar model is unknown or you don’t have its manual handy.
– You suspect hardware issues (defective cable/port), because settings changes won’t help if the physical link is failing.
If you tell me your exact Sony Bravia model and whether you’re using HDMI ARC/eARC or optical, I can point to the most likely menu path names and the highest-probability setting to change first.

Frequently Asked Questions
Why does my Sony TV have no sound from my soundbar even though the TV volume works?
This usually happens when the Sony TV is not sending audio to the soundbar, or the audio output is set incorrectly. Check that the TV audio output is assigned to HDMI ARC/eARC or Optical (depending on your connection) and confirm the soundbar is set to the matching input. Also ensure the TV is not muted and that “Speakers” is not set to TV Speakers instead of Audio System.
How do I fix Sony TV no sound from soundbar after changing HDMI ARC settings?
Start by turning off both the Sony TV and the soundbar, then unplug them for 1 minute and power them back on. Go to your Sony TV settings and set Audio System to your soundbar via HDMI ARC/eARC, then enable Bravia Sync/Control for compatible devices. Finally, cycle the soundbar input to the correct HDMI ARC channel and test sound from a different app or HDMI source.
What should I check if my soundbar works with other devices but not with my Sony TV?
First verify the connection type (HDMI ARC/eARC vs optical) and make sure you’re using the correct port on the TV and the soundbar. On the Sony TV, confirm the digital audio format/output settings (e.g., set to PCM for compatibility if needed) and disable any audio enhancements that could interfere. If you’re using HDMI, try a different HDMI cable and port labeled for ARC/eARC to rule out a cable or handshake issue.
Which audio output setting is best to get sound from a Sony TV to a soundbar?
For most modern soundbars, the best choice is HDMI ARC or eARC because it supports higher-quality audio and easier control through HDMI. If you don’t have ARC support, use Optical and ensure the TV’s optical output is enabled. In both cases, set the Sony TV’s Sound Output to Audio System (not TV Speakers) so audio is routed to the soundbar consistently.
What is the best step-by-step way to troubleshoot “no sound from soundbar” on a Sony TV?
Confirm the soundbar is powered on, the correct input is selected, and the Sony TV is set to the correct Audio System (HDMI ARC/eARC or Optical). Then perform a power reset (unplug TV and soundbar for 30–60 seconds) and run through the TV audio settings to ensure no mute or TV speaker routing is enabled. If the problem persists, update the Sony TV firmware and the soundbar firmware, and test with a different source to isolate whether it’s a TV audio output or source issue.
