Comment 11 for bug 732977

Another person with this bug: https://bugs.launchpad.net/mixxx/+bug/667651/comments/9. ASIO does seem to be a common denominator.

This might be related: http://www.portaudio.com/trac/ticket/108, ml thread http://thread.gmane.org/gmane.comp.audio.portaudio.devel/7006 (although the symptoms are different).
I'm going to see what sort of info I can get from Mixxx and ASIO on my own system, and see if the PortAudio devs know anything about what's going on (I _still_ don't get what PA is letting people open two ASIO cards when their website explicitly says it's not currently possible).
