Sorry, I see better investments of my time. I'd rather add GetPosition,
WHDR_BEGIN/ENDLOOP and waveOutRestart tests to winmm/tests/wave.c
The log file is there, and my explanation of the behaviour logical, with one
fault: at the time the second threads kicks in, there need not be more buffers
marked done, having >1 buffers marked done initially is enough. The first
thread returns device->first, and the second device->oldfirst->lpNext, so the
second buffer is notified twice.
That's exactly what the log shows: A9 is notified once, AB and AD twice.
Several things must occur concurrently to trigger the bug:
- several buffers marked done and
- waveOutWrite concurrent with feeder thread.
BTW, I already wrote 2/3 of a patch.
