It can handle 8000/ 11025/12000/16000/22050/24000/32000/44100/48000 Hz both mono and stereo, but only 16 bit samples. I won't work around that limitation in my WAV playback plugin. It only uses a simplistic playback engine and is meant as a 'preview' for PCM playback. With a more sophisticated playback engine, introducing the concept of (simple) software codecs, it will be possible to play 8 bit samples as well as simple compression schemes like ADPCM. This is clearly post-3.0 stuff, and I won't spend any more work on that before the playback engines (hopefully) get unified.
