A:Answer Hi New User,
Here are a couple troubleshooting tips that might help!
Check that your equipment supports the audio format you're trying to use. To see supported audio settings, use the Audio and Video Diagnostics tool on your Fire TV device:
Go to Settings on your Fire TV device.
Select Display & Sounds.
Select Audio/Video Diagnostics to see supported settings.
If the audio format you want to use is detected, but content being streamed is in a different audio format:
Use the test video at the bottom of the page to confirm that your equipment setup supports surround sound.Check that the content supports surround sound. If the audio format you want to use isn’t detected, it can’t be played with your current equipment setup:
Make sure that your equipment supports surround sound and is set up correctly. Some AVRs will require height speakers for Atmos support. Check the user manual that came with your devices or contact the manufacturer for more help. Make sure that you’re using a high-speed HDMI cable. Optical cables don’t fully support surround sound.Connect your Fire TV device directly to the HDMI input on your soundbar or AV receiver. You can use another HDMI cable to connect your soundbar or AV receiver to the HDMI ARC input on your TV. Change your audio format to a lower setting. Go to Settings on your Fire TV device and then Display & Sounds.
If the above fails, you can also do a factory reset your television.
I hope that helps!
