+Direct Sound Audio does not stop
+
+The Bug:
+DirectSound Audio does not stop because dsound_ctl_out does not end up calling IDirectSoundBuffer_Stop. This is due to a bug in dsound_get_status_out where the status flags returned from IDirectSoundBuffer_GetStatus are compared with DSERR_BUFFERLOST (an error code) rather than DSBSTATUS_BUFFERLOST (a status flag). The status is actually (DSBSTATUS_LOOPING | DSBSTATUS_PLAYING) and one of those flags happens to be set in the DSERR_BUFFERLOST value. As a result, dsound_get_status_out returns -1 and dsound_ctl_out exits before calling IDirectSoundBuffer_Stop.
+
+The Fix:
+A simple replacement of DSERR_BUFFERLOST with DSBSTATUS_BUFFERLOST in dsound_get_status_out. 
+Should be: "if (*statusp & DSBSTATUS_BUFFERLOST) {"
+
+Version Information:
+I was able to produce this bug in Qemu 2.9.0 and with the latest source pulled from git://git.qemu-project.org/qemu.git (commit 8dfaf23ae1). I was able to verify my suggested fix with the latest source.
+
+Guest OS:
+Discovered running Minoca OS v0.4 (www.github.com/minoca/os). Images at https://www.minocacorp.com/download/nightlies/latest-x86. The Qemu test images I tried (http://wiki.qemu.org/Testing/System_Images) didn't have an easy sound setup (was looking for 'aplay' or similar).
