Holy crap the op is almost right. When master fader is opened it does kill airplay. Serious bug. Can someone please post this to facebook. I cannot. In order to get airplay back, an audio app, with airplay support, needs to be opened after master fader. Keep in mind that when I say opened I mean it need to be shut down or forced closed. It needs to be started fresh. And if you have to force close master fader and restart it you will lose airplay. You will then have to force close the audio apps and reopen them to get airplay back. And again this needs to be done after the master fader app.
Maybe I opened my player up after running master fader. Which is why I have had no problems. Try it. Open an audio app, hit play and select airplay. Then open master fader. You will lose airplay. All airplay icons are gone, both in my player and in the quick select menu where it usually is.
Rr, Gio, or anyone with a Facebook account can you please post this bug to mackie? It seems like that's the only place to get them bug info. My account is blocked.
