After updating to aTV Flash to v4.4 I have no sound from my ATV. In the past when this happened I could play a music video and the sound would return, unfortunately this time there is no sound no matter what I do. Basically my ATV is now a brick. Any help would be greatly appreciated!
Can you try toggling the ‘Apple H.264’ option found in the Maintenance --> Settings menu?
You may also check to ensure your cables are connected securely.
Thanks for the suggestion about toggling the ‘Apple H.264’ option, it worked!
