Quick Fixes When Your Fire TV Stick Sound Is Not Working

If you are experiencing Fire stick sound not working suddenly, simple fixes are uncomplicated enough that you can try before troubleshooting further:

1. Check the Obvious. Volume, Mute: It may seem like a no-brainer, but most sound issues arise because a TV is accidentally muted or the volume is too low. If your firestick volume is not functioning correctly:

1. Press the volume up button on your firestick remote several times.
2. Check if your TV is muted.
3. Confirm external speakers or soundbars are powered on and set to the correct input.

2. Restart Your Firestick: One fix for many temporary glitches that cause no audio with Firestick is to simply restart the device:

1. Settings > My Fire TV > Restart.
2. Alternatively, unplug your Firestick from the power source for 30 seconds and plug it back in to the power.
3. Finally, wait a moment for the device to restart before trying sound again.

Audio Settings Adjustments for Firestick Sound Issues

More often than not, audio problems with your Firestick occur because of incorrect audio settings. Here is how to check/adjust audio settings: 

1. Digital Audio Format Settings

• Go to Settings > Display & Sounds > Audio > Digital Audio Format.
• Try the different formats in this menu between “Dolby Digital Plus” and “Dolby Digital”.
• If neither of those works, select “Stereo”.

This is also useful to do if you have a newer TV and/or audio system, and cannot use the format properly for each of these audio formats.

2. Audio Output Settings: In the event your firestick remote volume is not working, or you have other audio problems, look here: 

• Go to Settings > Display & Sounds > Audio > Audio Output.
• Select “TV Speakers if you use your Television speakers. 

If you use an external speaker or sound bar, make the appropriate selection, either HDMI or Optical.

Advanced solutions for ongoing Fire Stick audio issues.

If you are still having sound issues after trying all of the above solutions: 

1. Factory Reset Your Fire Stick: If all else fails, reset your device to the factory settings: 

• Go to Settings > My Fire TV > Reset to Factory Defaults.
• Confirm that you want to reset the device.
• Once the reset is complete, set your device up again.

Be aware that this will erase all apps and settings, and it should be a last resort. 

2. Check for System Updates: Software that is not up-to-date can cause firestick volume not working issues: 

• Go to Settings > My Fire TV > About.
• Click on “Check for Updates” or, if one is available, click on “Install Update”

Let your device update, and restart if necessary.
