48cb6b726c updated memory barrier comment urgh 2011-08-18 11:24:15 +00:00
rossb
f22cec3d45 moved memory barriers as per this thread: http://music.columbia.edu/pipermail/portaudio/2011-August/012803.html . use volatile because MSVC Read/WriteBarrier() intrinsics are just compiler barriers, but MSVC will insert memory barriers if you use volatile. see: http://msdn.microsoft.com/en-us/library/ms686355(VS.85).aspx 2011-08-18 11:19:36 +00:00

fa8a45c845 Fix removal of device property change listeners. 
This may fix some occasional memory corruption isses we were seeing in the loopback test.
I think the listeners may have gotten called after the stream was freed.

28397f5c4a Replaced MM timer with a high priority thread for audio compute, based on a patch by Dmitry Kostjuchenko. Reason: there is one global MM timer thread per process and doing audio compute in it was interfering with timer accuracy and also with running multiple DSound streams. The old MM timer based implementation is still available if you define PA_WIN_DS_USE_WMME_TIMER -- this may be removed in future. 2011-05-11 10:00:52 +00:00
