description:
libossaudio: Various OSSv4 fixes to allow reference programs to compile
- Define various new AFMT_*. These are not returned as supported
formats by SNDCTL_DSP_GETFMTS, because it would be very silly to
have Vorbis in the kernel.
- Implement PLAYTGT and RECSRC. For each NetBSD audio device
we only return one playback and recording source, "primary".
- Return preferred channel configuration in capabilities.
Either DSP_CH_STEREO, DSP_CH_MONO, or DSP_CH_MULTI
depending on the current hardware format.
- SNDCTL_DSP_HALT_* simply flushes the audio device.
