🔍 Common Sony TV Sound Problems & What Causes Them

🛠️ Detailed Step-by-Step Fixes for Sony TV Sound Issues
Fix 1: Check the Basics First
Before diving into settings, rule out the simple stuff:
- Check if the TV is muted — Press the Mute button on your Sony remote to toggle mute off.
- Turn up the volume — Press the Volume Up (+) button and confirm the on-screen volume bar appears.
- Check headphone jack — If something is plugged into the headphone port, the TV speakers will be disabled. Unplug it.
- Try a different remote — Your remote’s volume buttons may be faulty. Try the physical buttons on the TV itself.
Fix 2: Power Cycle Your Sony TV (Soft Reset)
A soft reset resolves most temporary glitches including sudden audio loss after firmware updates.
- Turn off the TV using the remote or power button.
- Unplug the TV from the wall socket completely.
- Wait 60 seconds — this fully discharges the capacitors.
- Plug back in and power on.
- Test the audio.
✅ This fix resolves Sony TV no sound issues in a large number of cases — especially after automatic software updates.
Fix 3: Check Audio Output Settings
Your Sony TV may be routing audio to the wrong output device.
- Press Home on your remote.
- Go to Settings → Display & Sound → Audio Output (or Sound → Speakers on older models).
- Ensure “TV Speakers” is selected — not “Audio System” or “Optical” — unless you’re using an external soundbar.
- If using a soundbar or home theatre: set to “Audio System” and confirm HDMI ARC or optical is connected properly.
Fix 4: Fix Sony TV Sound Cutting Out — Disable Auto Volume
If your Sony TV audio cuts in and out, the Auto Volume / Volume Leveler feature may be the culprit.
- Press Home → Settings.
- Navigate to Display & Sound → Sound → Advanced Settings.
- Find “Auto Volume” or “Volume Mode” and turn it OFF.
- Also disable “Dolby Audio Processing” temporarily to test.
Fix 5: Fix No Sound on HDMI — Check HDMI ARC Settings
No audio from your PlayStation, streaming stick, or soundbar via HDMI? Here’s how to fix it:
- Go to Settings → Channels & Inputs → External Inputs.
- Select “HDMI signal format” and ensure HDMI ARC is enabled on the correct port (usually HDMI 3 on Sony Bravia TVs).
- Enable “Control for HDMI (Bravia Sync)”.
- Disconnect and reconnect your HDMI cable firmly.
- Try a different HDMI cable — cables degrade over time and can cause intermittent audio loss.
Fix 6: Fix Sony TV Audio Delay / Lip Sync Issues
If the audio is out of sync with the video:
- Go to Settings → Display & Sound → Sound.
- Find “A/V Sync” or “Audio Delay” settings.
- Adjust the slider until audio matches the video.
- If using a soundbar, also check the soundbar’s own delay settings.
Fix 7: Clear App Cache for No Sound on Streaming Apps
No sound on Netflix, YouTube, or other apps on your Sony Google TV or Android TV?
- Go to Settings → Apps → See All Apps.
- Select the app with no sound (e.g., Netflix).
- Tap “Clear Cache” then “Clear Data”.
- Restart the app and test.
- Also ensure the in-app audio language is set correctly under the playback settings within the app.
Fix 8: Factory Reset Audio Settings
If none of the above works, reset only the sound settings without losing your other TV configurations.
- Press Home → Settings.
- Go to Display & Sound → Sound.
- Scroll to “Reset to Factory Defaults” or “Reset Sound Settings”.
- Confirm the reset and test audio.
Fix 9: Perform a Full Factory Reset (Last Resort)
A full factory reset will wipe all settings and apps. Only do this if all other fixes have failed.
- Go to Settings → System → About → Reset.
- Select “Factory Data Reset”.
- Follow the on-screen instructions.
- Set up the TV again from scratch and test the audio.
⚠️ Note: A full factory reset deletes all installed apps, accounts, and preferences.
🔧 When DIY Fixes Don’t Work — You Need a Sony TV Service Center
If you’ve tried all the fixes above and your Sony TV still has no sound, the problem is likely hardware-related, such as:
- Blown or damaged TV speakers
- Faulty audio IC / sound board
- Damaged HDMI ARC port
- Motherboard or T-CON board failure
- Damaged amplifier components
These require professional diagnosis and repair. Do not attempt to open your TV panel — Sony TVs contain components that can retain dangerous electrical charges even when unplugged.
