Verbose logging of AppleUSBAudio driver
Hi, I'm developing firmware for a USB audio device for which audio playback currently cuts off after about a second. The normal system logs via Console do not seem to throw any error related to USB audio (and nor do kernel-only logs via log stream --process 0). Is there a good way to dive deeper into what might be happening? Looking into the AppleUSBAudio driver, it contains a bunch of verbose "USB Sound assertion (%s) in %s at line %d\n" logs via IOLog(). Are they supposed to end up in the system logs under normal conditions, or does this require setting IOKit debug verbosity in boot-args? New to debugging Mac OS kernel things.. thanks for helping!
