Pull up following revision(s) (requested by nat in ticket #71):
sys/dev/audio.c: 1.359-1.366
sys/dev/audiovar.h: 1.56
No need to reset the audioinfo whem dealing with the hardware ring. This
avoids a panic with some audio devices.
Ok christos@.
--
sc_iffreq -> sc_frequency. NFCI.
Ok christos@.
--
Allow for bigger data types to mix into to avoid overflow.
--
Check hardare precision in vchan_autoconfig. Passes atf test again.
--
Use pustream params when clearing the next block in the mixring.
--
Check validbits against precision in vchan_autoconfig. At present
validbits != precision is not supported.
This change will most likely break autoconfig on vs(4), for these machines
the parameters can be set to the paramaters reported at attach time via
sysctl.
--
Don't start playback or recording on the hw ring only stream ring buffers.
--
Don't autoconfig for 24 bits precision. It does not work as yet.
