I think my Apple TV crapped out on me tonight. I've had it plugged in for a year and a half (haven't messed with anything) and today the sound went out. This has happened before and a simple reset fixed it...well not today. I unplugged everything and plugged it back in. I changed HDMI ports. I reset the Apple TV...nothing works. Everything else on my TV is working (TiVO, Xbox, Netflix TV App) but for some reason the sound isn't working. I messed with every audio setting within the Apple TV and nothhing works. The video is working perfectly...but no sound. Do you think it's done for? We were literally in the middle of watching a show and after pausing it the sound never came back.
