Hi,
I'd like to add to the previous report that similar issues are present in OSX (Sierra) builds of qemu-system-ppc.
In Mac OS 9.2 and OS X 10.3 guests, sound through the usb-audio device is unrecognisable.
After forcibly shutting down Mac OS 9.2 after it becomes unresponsive, qemu crashes. The OS X crash reporter says this:
