Sony TVs that display video from an HDMI device but produce no audio almost always have the TV’s audio output set to the wrong port or the HDMI/ARC settings out of sync. This happens when you switch devices, change connections, or use a soundbar/receiver without matching the HDMI audio mode. Work through the steps below to restore HDMI sound quickly and calmly.
If your Sony TV shows video from an HDMI device but outputs no sound, the fastest fix is to correct the TV’s Audio Output routing (TV Speakers vs Soundbar/Receiver), then force an HDMI re-handshake by power-cycling and re-selecting the HDMI input. This usually resolves “video works, sound doesn’t” issues caused by ARC/eARC routing changes, recent updates, or cable/port mismatches—especially as of 2026 when more Sony models support advanced audio formats through HDMI.
If your Sony TV’s HDMI audio went silent after an update, a soundbar addition, or a cable swap, you’re not alone—HDMI audio routing is sensitive to both settings and connection details. This guide walks you through the most common Sony settings and HDMI/ARC edge cases that cause “video works, sound doesn’t.”
This applies when you can see the picture from a connected device (set-top box, game console, Blu-ray player, PC, or streaming stick) but you get silence on your Sony TV for that HDMI input—especially after updates, cable swaps, or adding a soundbar/receiver.
Do fast checks first (before changing settings)
Start with connection and handshake resets, because Sony HDMI audio “no sound” is frequently caused by a stale negotiation between the TV and the HDMI device. In many real-world setups, the TV’s picture can still display even when the audio handshake fails.
– Reseat the HDMI plug on both ends, and try a different HDMI port on the Sony TV.
A partially seated HDMI connector can still carry video, while audio negotiation fails.
– Toggle inputs (switch to another HDMI, then back) to force the TV to re-handshake audio.
HDMI audio routing on a Sony TV often updates when the input is re-selected.
– Power-cycle both devices: turn off TV + HDMI device, unplug both for 60 seconds, then plug back in and test again.
This clears lingering audio routing states (including ARC/eARC and HDMI-CEC behaviors) that can persist after firmware changes.
As of 2026, HDMI troubleshooting works best when you treat the HDMI link as two parts: video transport (often continues even when audio fails) and audio capability negotiation (where mismatches can create silence). If the Sony TV still shows video but no sound after these checks, move to audio-output routing next.
Fix Sony TV audio output settings
Correcting the Sony TV’s Audio Output setting is usually the turning point, because the TV may be routing HDMI audio to the wrong playback path. Set it to match whether you want audio to play through the TV speakers or an external soundbar/receiver.
– In your Sony TV sound settings, set Audio Output to match your setup (e.g., TV Speakers for TV-only, or Audio System / Soundbar / Receiver when using external speakers).
If the TV is still set to an external audio device that’s off, muted, or disconnected, you’ll hear nothing.
– If you’re using a soundbar/receiver, make sure the TV is not still routing audio to the wrong output (a frequent cause of “no sound”).
For example: TV audio settings can continue using an older route even after you re-cabled to a new HDMI port.
– If available, verify the Digital Sound Output mode (PCM vs Bitstream) matches what your audio system can decode: mismatches can produce silence.
Bitstream formats require the soundbar/receiver to understand that encoding; PCM is the “safer” baseline for many systems.
To keep this decision structured, use this simple routing sanity check:
| Sony TV setting | Best for | What happens when it’s wrong |
|---|---|---|
| TV Speakers | No external audio device required | External soundbars may stay silent while TV speakers play audio |
| Audio System / Soundbar / Receiver | External speakers connected and powered | Silence if the external system is off, input-select mismatch, or routing is wrong |
The “why” matters here. Sony TVs commonly rely on HDMI audio capabilities and control signals (CEC/ARC/eARC) to decide where audio should go. When those signals aren’t aligned, the TV may keep sending audio to a path that isn’t receiving it—while still showing HDMI video correctly.
To anchor expectations across HDMI audio paths, here’s what tends to differ between ARC/eARC-style routing and other HDMI/optical paths:
7 HDMI/Audio Paths That Commonly Cause Sony “No Sound From HDMI” (2026)
| # | Audio path type | Typical format ceiling | Common Sony “no sound” trigger | Lossless passthrough |
|---|---|---|---|---|
| 1 | HDMI ARC (TV ↔ soundbar/AVR) | Lossy surround commonly | ARC port used incorrectly or ARC disabled | No |
| 2 | HDMI eARC (TV ↔ soundbar/AVR) | Higher-bandwidth audio formats | Wrong “ARC/eARC” HDMI socket or eARC off | Yes |
| 3 | HDMI (device → TV, TV → speakers) | PCM/lower-risk routing | Audio Output still set to “Audio System” | Yes |
| 4 | HDMI device → AVR (external receiver) | Broad HDMI audio support | AVR input selected wrong or format mismatch | Yes |
| 5 | Optical / Toslink (TV → soundbar/AVR) | Typically lossy surround / PCM stereo | Digital Sound Output set but optical cable/input mismatch | No |
| 6 | HDMI CEC-controlled routing (via ARC/eARC) | Depends on ARC vs eARC | CEC toggled off or control pairing lost after updates | No |
| 7 | Analog stereo (3.5mm/Red-White) fallback | Stereo only | Wrong input selected on speaker/bar/receiver | Yes |
Two standards context points that explain why Sony HDMI audio routing is so sensitive:
– According to HDMI.org, HDMI ARC (Audio Return Channel) is specified as part of HDMI 1.4 (published in 2009; commonly referenced as 2010-era availability).
– According to HDMI Forum, eARC is defined with HDMI 2.1-era capabilities (announced in 2017), which is why older soundbars may behave differently on the same Sony TV model.
– According to HDMI Forum, HDMI can carry LPCM up to 8 channels at 192 kHz/24-bit—so when the TV/receiver thinks it should output LPCM but can’t, you may get silence instead of sound.
Check the HDMI device’s audio format
Fix the HDMI device’s audio settings next, because the Sony TV can’t “invent” a format its audio path can decode. If the device outputs a Bitstream your soundbar/TV route can’t accept, you’ll see picture but hear nothing.
– On the connected device (console/receiver/PC), confirm the HDMI audio output is enabled and set to a supported format (commonly PCM or a supported Bitstream option).
If there’s an “HDMI Audio” toggle, leave it on.
– If you recently changed audio options (surround sound, “enhanced audio,” etc.), revert to a simpler setting and test again.
A temporary “PCM only” mode is often the fastest isolate step.
– Make sure the device isn’t set to “headphones” or another audio route that won’t output through HDMI.
This happens on some PCs and consoles after a driver update or audio device re-pairing.
A practical diagnostic approach is to change one variable on the HDMI device, then test the same Sony TV HDMI input. In my troubleshooting experience, the quickest pattern is: set Sony TV Audio Output correctly first, then set the HDMI device to PCM (or to “Auto” only if you trust the receiver to handle decoding).
Also watch for surround format mismatches. Many systems accept Dolby Digital (5.1), but fewer accept newer or lossless bitstreams when routed via ARC rather than eARC. As of 2026, that remains one of the most common sources of HDMI silence on Sony TV setups with soundbars.
ARC/eARC and soundbar/receiver gotchas
If the audio issue only happens with a soundbar/receiver over ARC/eARC, the problem is usually the port, the ARC/eARC toggle, or a CEC control conflict. Sony TV picture can still work while ARC/eARC fails, so don’t assume “video = fully working audio.”
– If the TV and soundbar/receiver use ARC or eARC, ensure you’re using the correct HDMI port and that ARC/eARC is enabled on both devices (names vary by model).
Sony models often label the ARC-capable socket clearly—use that exact one.
– Avoid using the “wrong” HDMI port for ARC: many TVs label ARC on a specific socket (often the one marked with ARC/eARC).
Plugging into another HDMI port can display video but prevent audio return.
– If audio is missing only when using ARC/eARC, try a different ARC setup first (or temporarily bypass ARC by using TV speakers or a standard optical/analog path if available).
Bypassing isolates whether the routing path (ARC/eARC) is the culprit.
Here’s the analytical way to think about ARC/eARC on Sony TVs: ARC/eARC is not just “another HDMI connection.” It’s an audio return mechanism with its own compatibility expectations. When you add a new soundbar or update firmware, the handshake may select a different audio mode or fail to re-negotiate.
Also confirm volume/mute behavior on both ends: some soundbars mute when they detect no valid audio bitstream, and some Sony TV modes keep audio routed externally even after you switch inputs.
What can go wrong (common mistakes and edge cases)
Most “no sound from HDMI” cases are routing or negotiation failures, not broken hardware. Still, a few edge cases can keep silence going even after correct settings are applied.
– Setting Audio Output to an external system while the external system is off/unpaired can look exactly like a broken HDMI audio path.
Example: if the soundbar is in standby, the Sony TV may keep routing audio outward.
– Using an HDMI cable that’s physically seated but not fully clicked, or a lower-spec cable, can cause unstable audio handshake.
Video may remain, while audio formats don’t reliably negotiate.
– Some TV/device combinations require re-handshaking after firmware updates—if the issue started after an update, prioritize output-mode and ARC/eARC checks first.
In 2025–2026, firmware rollouts frequently change how Sony TVs interpret “Auto” audio formats or ARC control states.
The safest troubleshooting mindset is root-cause isolation: change one thing, test, then move to the next likely cause. If you keep flipping PCM/Bitstream, ARC toggles, and device audio output all at once, it becomes hard to know what actually solved the problem.
Verdict: what to try next (and who should skip extra steps)
Start with: (1) correct Audio Output on the Sony TV, (2) power-cycle + reselect the HDMI source, and (3) verify the HDMI device’s audio format. Move to ARC/eARC settings only if you’re using a soundbar/receiver through the ARC/eARC connection—otherwise you’re likely solving the wrong problem.
Downsides: changing audio formats (PCM/Bitstream) without knowing what your sound system supports can temporarily reduce surround features or still not fix the issue if the output routing is wrong. If you’re not comfortable navigating menus, don’t keep flipping multiple settings at once—change one thing, test, then proceed.
Who should skip deeper ARC/eARC dives: If you’re using TV speakers, headphones, or an optical path, don’t spend extra time on HDMI ARC port labels—your issue is almost certainly the Sony TV output routing or the HDMI device’s audio output mode.

Frequently Asked Questions
Why does my Sony TV have no sound when I connect a device through HDMI?
This usually happens when the audio output is set incorrectly on either the HDMI source device or the Sony TV. It can also be caused by an HDMI handshake issue, a faulty HDMI cable, or a mismatch between supported audio formats (such as Dolby/DTS). Start by checking that the TV is using the correct HDMI input and that the volume is not muted or routed to the wrong speaker. Then verify the connected device’s audio settings to ensure it outputs sound via HDMI.
How can I fix no sound from HDMI on a Sony TV using the TV settings?
Open your Sony TV’s Settings and navigate to Sound (or Audio System) to confirm the speaker output is set to TV Speakers or the correct external audio device. Also check Audio Output to ensure it matches your setup (e.g., HDMI ARC/eARC vs Optical vs Bluetooth). If your TV has an “Audio Language/Format” option, try switching between Auto and PCM to resolve audio format incompatibility. After changes, power-cycle the TV and the HDMI device to refresh the HDMI audio handshake.
What HDMI audio settings should I change on my streaming box, PlayStation, or cable receiver?
On the connected HDMI device, set the audio output to HDMI and choose a format the Sony TV supports—often PCM is the safest option. If there are settings like “Dolby Digital,” “Bitstream,” or “HDMI Audio,” try switching from Bitstream/Auto to PCM Stereo, then test playback. Some devices default to optical or TV speakers; make sure they are not still routing audio to a different connection. Reboot the device after adjusting audio settings so the HDMI handshake renegotiates properly.
Which HDMI cable and port settings work best to solve Sony TV no sound from HDMI?
Use a known-good High-Speed HDMI cable (or Ultra High-Speed if available) because damaged or low-quality HDMI cables can cause video-only audio. Plug the device into a different HDMI port on the Sony TV to rule out a port-specific problem, and avoid using HDMI splitters if you’re troubleshooting audio. If you’re using HDMI ARC/eARC with a soundbar or AVR, ensure the cable connects to the TV’s ARC/eARC-labeled port and that ARC/eARC is enabled in both the TV and audio system. Test again with the simplest setup first: one device directly into one HDMI port.
What’s the fastest troubleshooting method when Sony TV shows picture but no sound over HDMI?
Do a quick power reset: turn off the Sony TV and the HDMI device, unplug both for 30–60 seconds, then plug them back in and power on in that order. Next, switch to the correct HDMI input/source on the TV remote and confirm the TV isn’t muted and the volume works. If there’s still no sound, run a format change—set the HDMI audio output on the device to PCM Stereo, then retest. Finally, try the same device on another HDMI port (or another HDMI device on the same port) to pinpoint whether the issue is the cable, port, or audio configuration.
