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

9c4c92fef6 alsa: 
- implemented dynamic ALSA loading, you shall define PA_ALSA_DYNAMIC when compiling PortAudio library, by default PortAudio will use compile time linkage;
- added PA_ALSA_PATHNAME define to redefine ALSA library path and filename to some other name and location, has effect only together with PA_ALSA_DYNAMIC;
- added extension function (PaAlsa_SetLibraryPathName) which allows to set ALSA library path and filename during application run-time overwriting default set by PA_ALSA_PATHNAME during compilation;
- added API compatibility with Android OS (although ALSA may not be available on your device and usually requires 'root' access rights to open an audio device), some missing ALSA functions are replaced with stubs (needs more input from interested parties), to compile on Android you need to add ALSA headers (get it from Android GIT source-code tree) to compiler's searchable path.

4318a7556b alsa: 
- fixed callback thread to exit normally if error condition was satisfied during stream processing (OnExit wasn't called), it was possible cause of crash if error happened inside the thread
- modified processing thread to timeout during poll() within around 2 seconds instead of 64 milliseconds, this will help to fix problems on systems with low processing power and possible CPU overloading, like portable ARM devices
- timeout of poll() will not cause stream to stop but will cause Alsa stream restart, poll timeout will now set 'xrun' event to 1

148784f3c7 Commit fix for crash during full-duplex operation with PulseAudio. Reported by Al Dimond, fix proposed by Ross Bencina, acked by Dmitry Kostjuchenko.
