[alsa-devel] [PATCH 4/8] ALSA: hda - Use generic parser for CA0110 codec

Takashi Iwai tiwai at suse.de
Tue Jan 8 12:50:45 CET 2013


CA0110 codec is a fairly straightforward hardware implementation,
and we can use the generic parser almost as is.
Just set spec->multi_cap_vol flag to follow the current behavior.
