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).
