--- Comment #1 from Jörg Höhle hoehle@users.sourceforge.net 2011-09-19 09:41:48 CDT --- That bug is caused by waveform.c:WOD_PushData filling up the whole buffer with silence when the queue is empty. The queue is empty on MacOS because of bug #28093.
See bug #27937 for another issue caused by writing silence.
