Went to watch a movie tonight and get no sound from ATV - tried all sources (movies, TV, radio)
When I try to stream music from the iMAC using the i-Tunes radio and setting speakers to ATV it initially said that someone else was using it to choose another speaker but this has since gone away - but I still get no sound.
All other sources on the TV work fine.
any ideas appreciated
3.06 GHz Intel Core 2 Duo 27" iMAC, Mac OS X (10.6.2), 4GHz RAM, HK Soundsticks
If the problem started suddenly and you can't clear it by rebooting the ATV, it could be an indication that an audio component in the ATV has failed. If it's still under warranty, take it to an Apple store or call AppleCare. Make sure the problem isn't your A/V receiver first, though.
