Hi,
I am seeing a hung with AudioUnitSetProperty. Taking a sample of the app, it seems another thread is also accessing
AUAudioFilePlayerEntry. Any idea where is DLSMusicDeviceEntry coming from(looks like system call)? Is there any check before AudioUnitSetProperty that I can use to prevent entering the hung situation? Thanks.
