            Status: UNCONFIRMED
          Severity: trivial
          Priority: P2
         Component: mmdevapi

Since Wine-1.3.26 I can hear the audio test even though I have disabled all
sound drivers in winecfg's audio tab. Actually, I have only Alsa available
because OSSv4 is not installed on my system.

Reverting the patch fixed the problem (audio test gives an 'Audio test failed!'
error message when no sound drivers selected).
