Slight audio glitch when pressing the sleep/wake button on iPhone

Slight audio glitch when pressing the sleep/wake button on iPhone

My application is playing audio using kAudioUnitSubType_RemoteIO similar to the aurioTouch sample and everything works great
except that I'm experiencing a slight audio glitch when pressing the sleep/wake button on the iPhone. The iPod app on the iPhone doesn't do this and a couple of other iPhone audio apps
doesn't either so there must be something that I'm missing?


When sleeping, the inNumberFrames in the render callback changes from 1024 to 4096 if that's related to this problem?

There are plenty of frames in the buffer that is generated by the feeder thread so it's not related to that.

This is on an iPhone 3G with OS 2.1.1 and I'm building against SDK 2.2

Any advice?

Rolf
