Losing audio on a Sony Bravia is usually a settings or connection problem, not a blown speaker. Whether you get total silence, sound only through external speakers, or audio that cuts out, the checks below will usually restore it in minutes.
Quick Answer
If your Sony TV has no sound, first confirm it isn’t muted and the volume is up, then check the audio output setting: Settings > Display & Sound > Audio output > Speaker, and set it to “TV speakers” (not external) if you aren’t using a soundbar. A power-cycle and verifying the HDMI ARC connection fixes most remaining cases.
Common Causes
- Muted or low volume: the simplest and most common cause.
- Wrong audio output: set to external/soundbar when none is connected.
- HDMI ARC/eARC issue: handshake failure with a soundbar or AV receiver.
- Digital audio format mismatch: the device can’t decode Dolby/DTS passthrough.
- App or source problem: a single app outputs no audio.
- Software glitch: Android/Google TV audio service hangs.
- Hardware speaker fault: rare, but possible.
Step-by-Step Fix
- Check mute and volume: Unmute and raise volume; test with a different source.
- Set audio output: Settings > Display & Sound > Audio output > Speaker > TV speakers.
- Power-cycle: Unplug 60 seconds, hold power 15 seconds, replug.
- Check HDMI ARC: Use the HDMI port labelled ARC/eARC and enable Control for HDMI (BRAVIA Sync).
- Change digital audio format: Set Digital audio out to PCM if a soundbar gives no sound.
- Test per app: If only one app is silent, clear its cache or reinstall it.
If your TV speakers are weak or failing, a soundbar is an affordable upgrade that also bypasses the problem entirely:

When to Call a Technician
If you get no sound from the TV speakers even after a factory reset, with correct settings and no external device connected, an internal audio board or speaker fault is likely and needs service.

Frequently Asked Questions
Why does my Sony TV have no sound suddenly?
Usually a changed audio output setting or a muted output. Check Audio output is set to TV speakers and that volume isn’t muted.
How do I fix HDMI ARC no sound on a Sony TV?
Use the ARC-labelled HDMI port, enable Control for HDMI (BRAVIA Sync), and set Digital audio out to PCM if the soundbar still has no sound.
Why is there no sound on only one app?
That app’s audio process has glitched. Clear its cache or reinstall it; other apps working confirms the TV hardware is fine.
Will a factory reset restore sound?
It can clear a stuck audio service. If sound is still absent afterward with correct settings, the issue is hardware.
