So I just got a dedicated external DAC to run the optical from my airport express to. Now in iTunes whenever I start a song when there hasn't been anything playing for a few seconds I get the "No speakers are connected" message and the song starts playing anyway, but its really annoying because I have to click 'OK' every time. I know what is happening - the airport express stops running any digital signal when no music has been playing for a while, my DAC starts cycling through its inputs to check for a live signal, and then when I press play again it takes a moment for the airport express and the DAC to sync up and start playing. I don't have to press play twice, I just press play, get the stupid "no speakers connected" message, and the music starts playing anyway. ...so since iTunes reporting this to me is certainly not helping - is there any way to just tell it to shut up and play regardless of if it thinks there are speakers hooked up or not? ...or better yet, is there a way to force the airport express to maintain a digital sync with an external DAC even when no songs are playing? Thanks!
