Parallels and USB audio device detection

[3lysium]

I've had this problem on my Macbook Pro (2011) for some time now and am in need of help.

Whenever I have Parallels running, USB audio devices are not detected in Snow Leopard audio devices. This has been a problem both on Parallels 7/Win XP and still since upgrading to Parallels 8/Win 7.

Seems to affect any USB audio device, so far this includes:
- M-Audio Torq Xponent
- Traktor Audio A6
- Pioneer DJM850 mixer

Workaround: If I reboot the macbook and connect the device (without starting parallels) then it will register and work as normal.

Anyone have any ideas?

I think I've solved this following steps this article:

There seemed to be a problem with entries in the system sound config file. Not the sort of issue I would expect from the worlds most advanced operating system.

I can now select USB sound devices when Parallels is running.
