Kyle, Jens et al,

I fixed it! What I did was instantiate an AVAudioPlayer and have it play a wav of silence (best imagined as a device in a Maxwell Smart movie) right before I shut down stream A, and stop it right after stream B's audio queue is set up and started. This way there is always _something_ playing audio in the background, so iOS4 doesn't suspend me ;-)

Result: my app continues in the background, even between streams :-)

Regards,

John
