I'll ty the downgrade and see what happens. I use my ATV mostly to stream music from iTunes to my stereo amplifier via Airplay and optical out and I'm finding that when I first connect to the ATV I get no sound. If I switch the sound to the computer and then back to the ATV it works. I've not had any problems with sound to the amplifier when I've streamed movies from the iTunes store or elsewhere.
That's what I've been calling the Airplay two-step bug. It too is new with 4.4.x, and reverting to 4.3 solves it. Some people have said the latest iteration of 4.4.x fixed the optical out issue but left Airplay two-step intact. Thus, it could appear that optical out isn't working, but doing the Airplay two-step should reactivate it, at least until the ATV goes to sleep again. Again, 4.3 works properly, and none of that is necessary.
I stream from my Touch 4th gen to the ATV, and iOS 5.0.1 on my Touch and 4.3 on my ATV work great. Compared to previous iOS versions, 5.0.1 keeps my Touch on Airplay between uses, which is nice; earlier versions would always go back to the Touch for output, and I'd have to reselect the ATV every time.
