Prime Video No Sound
Amazon Streaming & Shopping
Severity: ModerateWhat Does This Error Mean?
Amazon Prime Video with no sound means the audio stream is muted, blocked, or failing to decode on your device. The most common causes are the device being muted, an incompatible audio output format (like Dolby Atmos), or the app needing a refresh. Check your device volume, the player's audio track settings, and your audio output format. Switching the audio track from Dolby Atmos to Stereo resolves this on many TVs and soundbars that do not fully support Atmos.
Affected Models
- Amazon Prime Video Web
- Amazon Prime Video Android
- Amazon Prime Video iOS
- Amazon Fire TV
- Amazon Fire Stick
Common Causes
- Your device is muted or the volume is set to zero in the system settings
- The Prime Video player has a muted audio track — the player has its own audio controls
- Dolby Atmos or Dolby Digital audio format is selected but your device does not support it
- The wrong audio language track is selected and it may be silent or contain only audio description
- A Bluetooth speaker or headphones disconnected mid-playback and left the audio output with no destination
How to Fix It
-
Check your device volume. Use the volume buttons on your TV remote, phone, or tablet to raise the volume. Confirm the device is not on mute (a mute icon in the corner of the screen).
Some TVs have separate volume controls for external speakers and internal speakers. Make sure the active output is turned up.
-
During Prime Video playback, tap the screen and open the audio/subtitle menu (speech bubble icon). Check which audio track is selected and switch to a different one — try Stereo (2.0) if Dolby Atmos or 5.1 is selected.
Dolby Atmos tracks are sometimes silent on devices that partially support but do not fully decode Atmos audio.
-
Restart the Prime Video app and your device. Exit Prime Video completely, power cycle your TV or streaming device, and relaunch Prime Video.
On Fire TV: Settings > My Fire TV > Restart. On smart TVs, unplug from the wall for 30 seconds.
-
Check your TV or AV receiver audio output settings. If using HDMI ARC or optical audio output to a soundbar or receiver, ensure the audio format is compatible. Set the TV's audio output to PCM or Stereo to test.
Navigate to your TV's Sound settings and look for Digital Sound Output or Audio Format. Change it from Dolby Digital to PCM and test.
-
If using Bluetooth speakers or headphones, check they are connected and set as the active output device. Bluetooth devices sometimes disconnect silently, leaving audio going nowhere.
On Fire TV: Settings > Controllers and Bluetooth Devices > Other Bluetooth Devices — check your speaker is connected and listed.
-
Clear the Prime Video app cache and data. On Fire TV: Settings > Applications > Manage Installed Applications > Prime Video > Clear Cache and Clear Data. Restart and test.
Clearing data requires signing back in. Have your Amazon email and password available.
When to Call a Professional
Prime Video audio issues are always user-fixable. No professional help is needed. If there is no sound from any app or source on your TV or device, the device's speakers or audio output may need service. Contact your TV manufacturer's support if no apps produce sound after restarting the device.
Frequently Asked Questions
Why does Prime Video have no sound on my soundbar but works through TV speakers?
Your soundbar and TV are using HDMI ARC, optical, or Bluetooth to transfer audio. If the audio format selected (such as Dolby Atmos) is not supported by your soundbar, it sends no audio rather than degraded audio. Set your TV's digital audio output format to PCM or Auto and test again. Also check that the correct HDMI input on the soundbar is selected and the soundbar is not on mute.
Sound works on other apps but not Prime Video — why?
Prime Video uses Dolby audio for many titles by default. If other apps using standard stereo audio work but Prime Video does not, the problem is with Dolby audio processing on your device. Go to Prime Video playback settings and manually select Stereo instead of Dolby Digital or Atmos. This tells Prime Video to deliver the audio in a simpler format your device can handle.
No sound on Prime Video after a Fire TV update — what happened?
Fire TV software updates occasionally change audio routing or reset audio format settings. After a Fire TV update, check Settings > Display & Sounds > Audio > Dolby Digital Output and change it from Dolby Digital Plus to Dolby Digital or Off. Also check that your HDMI connection is fully seated — updates sometimes reset HDMI-CEC settings.
