apple iphone is limited to one sound if compressed
The apple specs clearly state that the hardware accelerator chip that is handling sound decompression can only handle one stream at a time, and so if you want to mix two or more tracks of sound they gotta be in linear PCM format or IMA4:1 otherwise no go. I can live with one track of MP3 background sound, and use PCM for my bleeps, etc.
I just couldn't get a compressed sound to play using their SpeakHere example, evidently you have to add some additional calls to get it to work.
