Apple TV Audio
Step 1. Basic Apple TV audio troubleshooting
- Check if the volume on your television or receiver is reduced or set to mute. Use the TV or Receiver remote and refer their manual to enable sound.
- Check if the connection between your Apple TV to television/home theater is secure and they are connected to power.
- Verify that the source on your audio receiver is set to the Apple TV input. Check the receiver’s or speaker’s manual to find out how to change the source.
- If none of these helped, try rebooting your Apple TV. Just press and hold (Menu + Down) buttons on the Apple remote for 6 seconds and your Apple TV will restart.
Step B. Troubleshoot the Apple TV audio peripherals
- In most cases you would need to just check the HDMI as this is normally what we use in the school system.
step is only for those users who have a third party home-theater set,
audio receiver or speaker set up as the Apple TV sound output. In this
case, you are probably using the optical audio output from the Apple TV.
Try disconnecting the optical digital audio port and connect the Apple TV directly to your television via HDMI only.
- If the audio issue is now resolved, your audio peripheral or the optical audio cable is defective.
Step C. Troubleshooting the Apple TV audio settings
- On the
Apple TV, Go to Settings > Audio & Video
Change the Audio Output setting from Auto to 16 bit.
- Change the Dolby Digital from Auto/On to Off.
