"play.gain" behaves like an alias of "outputs.master" mixer
item.  However, azalia diver doesn't provide "ouputs.master" for
any codec at this moment.

High Definition Audio doesn't define the master volume, and we
need to investigate what is the master volume on each of codecs.

As for ALC882, "outputs.green.*" or "outputs.heaphones.*", and
"outputs.mix0c" are important for playback volume.  I don't know
about STAC9221D (0x8384/0x7683) codec.
