sys/dev/sound/usb uaudio_pcm.c
Log:
MFC: [stage: 2/7]
Various fixups, especially for the upcomming High Definition Audio
commit.
1) sys/dev/sound/pcm/sound.h
sys/dev/sound/pcm/channel.c
* Be more specific: SD_F_SOFTVOL -> SD_F_SOFTPCMVOL
2) sys/dev/sound/pcm/mixer.[ch]
* Implement
mix_setparentchild()
mix_setrealdev()
mix_getparent()
mix_getchild()
The purpose of these functions is implement relative volume
adjustment, such as to tie two or more mixer device into a
single logical device. Usefull for the upcoming HDA driver
and few AC97 codec where the master volume "vol" need to be
implemented using this logical manner.
3) sys/dev/sound/pcm/ac97.c
* ditto #1
sys/dev/sound/pcm/usb/uaudio_pcm.c
* ditto #1, hook "pcm" as logical child of "vol" if the real
control does not exist.
