Use "Independent HP" just because patch_via.c already used it so it
is
better to use a standard name for all hda codecs
Yeah, I know. But this name is confusing, so better to change in patch_via.c as well.

To force pulseaudio to get the correct subdevice for via codec, you may
need
to add "subdevice 0" to HDA-intel.conf
since subdevice 0 support multichannel but subdevice 1 only support
stereo
playback.pcm { type softvol slave.pcm { type hw card $CARD
subdevice 0 } control { name "PCM Playback Volume" card $CARD }OK, fixed now. Thanks.
Takashi
But dmix still fail and you cannot use dmix with subdevice 1
I'd name it differently, e.g. "Headphone Stream Mode" taking "Slave" and
"Independent", or such. An enum with "ON" and "OFF" is no sensible choice.
The main point is how can the user find out which subdevice or device is used for "Headphone Stream"
Neither "aplay -l " nor "aplay -L' provide any useful information to the user
