A misconfigured Apple TV can result in a device with no sound. By default, most of the Audio & Video settings are set to Auto and for the majority of users this works fine. However, some of the auto setting can be the source of the no audio problem. The first method I try for any Apple TV issue is to reset the device (Hold the Play & Menu button simultaneously on the remote for 6 seconds). Sometimes a reset will do the trick.

Reset Audio Driver for Macs
1. On your Mac, open the Launchpad, go to ‘Other’, and open ‘Terminal’
2. Enter the following line in Terminal:
sudo kill `ps -ax | grep ‘coreaudiod’ | grep ‘sbin’ |awk ‘{print $1}’`
3. This will reset the audio driver and should resolve the no sound issue
Couldn’t get the above to work on Mavericks, so I did my own version of it, and it works perfect!!
sudo kill `ps -ax | perl -ne ‘print if /sbin\/coreaudiod/’ | perl -ne ‘print $1 if /(\d+)/’`
after many fixes I went to the modem and checked and reset it to allow apple tv, this fixed the no sound problem .
Start by making sure your cables are connected. For some reason my cable was broken, (optical).
Thank you holding the two buttons down together did get it to restart and sound is back. I have the 2015 version.
Thank you for the trouble shoot. I just held the menu and play button down for 6 seconds, the light on the apple tv blinked a few times and the system rebooted. From there, back in business.
That works perfectly for me. Thanks
The reset worked perfectly. Many thanks.
I just selected TV via IR in settings -> remote devices -> select volume control and it works.
Thank you!!
Reset worked! Thank you!
Nothing of the above worked – so I took the “long way” and reset to factory setting + update and now I have sound playing in the background while reinstalling all my apps 🙁
