Frequently Asked Questions
Why does my Fire Stick suddenly have no sound?
This is usually caused by an incorrect audio setting, a loose HDMI cable, or a minor software glitch on your Firestick. Restarting your device and rechecking your audio output settings resolves the issue in most cases.
What should I check first if my Fire Stick has no sound?
Press the volume up button on your remote and make sure your TV is not accidentally muted. If the issue continues, unplug the HDMI cable and firmly plug it back in to rule out a loose connection.
Why did audio stop working on Fire Stick after an update?
A software update can sometimes reset your audio settings back to default on Fire Stick. Go to Settings, select Display and Sounds, then Audio, and recheck your Dolby Digital and Surround Sound settings to restore audio.
Where do I find the sound settings on Fire TV Stick?
Fire TV Stick sound settings are found under Settings, then Display and Sounds, then Audio. From here you can adjust Dolby Digital Output, Surround Sound, AV Sync Tuning and Advanced Audio options.
Should I use Dolby Digital or PCM on my Fire Stick?
Use Dolby Digital Plus if your TV or soundbar supports it for the best possible audio quality on Fire Stick. If your device does not support it, switch to PCM as it is the most universally compatible audio format.
Can restarting Fire Stick fix sound issues?
Yes, restarting your Fire Stick clears temporary software glitches that often cause audio problems. Go to Settings, select My Fire TV, click Restart, and check if sound is restored once the device reboots.
Can an HDMI port cause no sound on Fire Stick?
Yes, a faulty or incompatible HDMI port can prevent audio from coming through on Fire Stick. Try unplugging and firmly replugging the cable, or switch to a different HDMI port on your TV to see if sound is restored.
How do I check if my TV mute is causing no sound on Fire Stick?
Press the Mute button on your TV remote to toggle it off and then press the volume up button on your Firestick remote. If sound returns, accidental muting was the cause of the issue all along.
How do I change the audio output device on Fire TV?
Go to Settings, select Display and Sounds, then Audio, and adjust the settings to match your connected output device. If you are using an external soundbar or speaker, make sure it is confirmed as the active audio device in both your TV and Fire TV settings.
