Hi, We encountered few instances where my applicaton was unable to start audio device(build-in Mic and build-in speaker). When I left Macbook Pro in sleep over night, I may experience this issue on the next day when I start audio device. I have checked system log, and found there is error message: ”HALB_IOThread.cpp:237:_Start: HALB_IOThread::_Start: IO is still disabled after waiting"；when my application initialize audio device to capture and play audio through Core Audio Framework's AudioDeviceStart API. I'd like to know what does this log mean? What will trigger this error message? What will happen after this?
Thanks
