Restart Your Fire TV

Restarting your Fire TV is often the simplest solution to fix audio issues. Sometimes, a basic reboot can resolve connectivity problems. To restart, press and hold the navigation ring button on your remote for 5 seconds to open the Power Options menu, then select Restart. Wait for the device to turn back on.

Allow the Fire TV to load completely before assessing the audio. A quick fix like this could be all it takes to resolve the problem.
Check Audio Settings and Output

The first step to fix audio issues is to check if the audio is turned on. Navigate to the Fire TV's Settings menu and select the "Display & Sounds" option. From there, ensure the "Stereo" or "5.1" option is selected, depending on your setup. This may not seem like a straightforward solution, but it's surprising how often a simple toggle fix solves the problem.
- Also, check that the correct HDMI output is selected for your TV. You can do this by going to Settings > Device > Preferences > Display & Sounds and selecting the correct HDMI port number.
- Verify that the TV's audio settings are set to the correct output (e.g., HDMI, Optical, or Coaxial). You can find these settings in your TV's menu.
