d714962621 wasapi: 
- fixed int24 Mono to Stereo mixer (affects Mono streams starting in Exclusive mode)
pa_converters: 
 - avoid using 64-bit integer math for Int24_To_Float32 and Int24_To_Int32 under x64 Posix platforms (long is 64-bit there), now using explicit PaInt32 type

14a79e0e89 wasapi: 
- fixed bug when Exclusive mode was wrongly opening Stereo stream if Mono stream was requested (note: WASAPI device usually does not support Mono in Exclusive mode), resulted in distorted sound
 - implemented workaround for WASAPI limitation - in Exclusive mode Mono stream is not supported: now PA creates internal audio device in Stereo mode, and after callback call Mono data is mixed into Stereo output, this workaround is not supported for Blocking mode. all this is done transparent for user, automatically.

779ef401ac wasapi: fixed initialization stage of PaWasapi_Initialize() which was returning error if WASAPI wasn't found (for example under Windows XP), this was causing PA's whole initialization to fail completely 2010-03-04 11:02:06 +00:00
