Thank you Christopher. I had read similar articles and tried turning off Bluetooth but it didn’t help. However, I just tried it again and it seems to have worked. Also, I had the Raspberry Pi sitting on my desk next to my computer when I was having those problems. Once I moved it to the other room with my stereo I haven’t has as many drop outs. I streamed a station from Pandora and Airplay didn’t drop out before Pandora got to that „Are you still listening?“ page. So that’s an improvement.
The only time Airplay consistently drops out now is when I’m watching a YouTube playlist. It seems that at just about every video in the play list Airplay drops. Maybe it is the browser I’m using. I’ll keep experimenting and update this thread.
