freebsd-dev/sys/dev/sound
History
Ariff Abdullah 7699548f1b 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 (such as AD1981B) where the master volume
     "vol" need to be implemented using this logical manner.
3) sys/dev/sound/pcm/ac97_patch.[ch]
   * Patch for AD1981B codec to enable (automuting) headphone jack sense.
4) sys/dev/sound/pcm/ac97.c
   * Implement proper logical master volume for AD9181B codec
     through various mix_set{parentchild,realdev}(). Tie both
     "ogain" (headphone volume) and "phone" (speaker/lineout) to
     a logical "vol".
5) sys/dev/sound/pcm/usb/uaudio_pcm.c
   * ditto, for "vol" -> { "pcm" }.
