This is a patch that makes WINE detect snd_usb_audio mics and assign
them a mixer and working master control. See bug #12706 for more
information about this problem: http://bugs.winehq.org/show_bug.cgi?id=12706
I wasn't able to test it completely because I wasn't able to switch my
default input device to the USB mic and no one in IRC is helping with
this, but it might make things work because theoretically the only
problem was that WINE was ignoring devices that looked like
snd_usb_audio's microphones. I suggest that someone who CAN get
snd_usb_audio mic as their default test it out and confirm, I would
really appreciate that.
Thanks to all in IRC who helped me get things this far, especially
mlankhorst.
This patch is based against the current git HEAD, eaa227c12d8bb. I've
also posted it at the aforementioned bug.
