--- Comment #9 from Matthew Stapleton matthew4196@gmail.com 2011-09-25 02:59:50 CDT --- I was able to properly fix the problem by going into regedit and in HKEY_CURRENT_USER\Software\Wine\Drivers, removing an old Audio string entry that had the value "pulse". Now the driver autodetection works properly.
