Issue: No sound when playing a video from a digital media player connected through HDMI, such as an Apple TV or Roku
Change the audio output on the media player either to a "PCM" variant, Stereo, or disable surround sound audio. The exact setting will vary depending on your device and the application you're using to stream media. Several examples are provided below.
Apple TV:
- From the Apple TV home screen, select Settings.
- Select Audio & Video.
- Select Dolby.
- Select Off to disable Dolby.
Android-based media players (TiVo, Amazon Fire TV):
- For Netflix, change the Netflix app audio options from surround sound to Stereo.
- Check in the device's settings if anything may be causing it to default to 5.1 audio.
