Hi, This has been driving me insane all day.
I'm trying to record from a certain USB audio microphone at 192k sampling rate native format is signed integer 16bits. AudioUnitRender in input callback returns kAUGraphErr_CannotDoInCurrentContext. Code works perfectly with internal microphone. Tried another USB sound interface I had. It's supported rates are 44.1k and 48k also signed 16 bit according to HALLab. Got same problem. Tried USB hub in between - same problem. I'm starting to suspect a problem with USB audio in Sierra. Some googling reveals people are also having problems with USB headsets. Just updated to 10.12.5 but it didn't solve the problem. I'm using a MacBook Pro (Retina, 13-inch, Late 2013). The USB audio devices works as intended on other hardware. Anyone solved this? --Albin _______________________________________________ Do not post admin requests to the list. They will be ignored.
