Multistreaming Playback using Front Panel Headphone with realtek codec

Request for testers to test the patch

Multistreaming allows you to listen to one audio source through the back
panel speakers and a second audio source through front panel headphones or
speakers.

Hardware requirement
1) 10 channels realtek codec (e.g. alc892) which already work with
model=auto
2) Headphone at front panel and Line out at rear panel

"hw:0,0" is used for the rear panel audio jack
"hw:0,2" is used for the front panel headphone when "Independent HP" is
switched ON

Add an "Independent HP" switch to turn this feature on/off for desktop for
those HDA codec

Test:
1) speaker-test -c 8 -t wav -Dhw:0,0
2) speaker-test -c 2 -t wav -Dhw:0,2

It will need modification to support this feature for those desktop with 8
channels codec

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.

I think it just partially works with model=auto

according to your alsa-info.sh

There are two sets of capture volume/switch and input sources controls but
only one capture device

you can use hda-analyzer to change the volume slider and mute switch in the

Use "Independent HP" just because patch_via.c already used it so it is
better to use a standard name for all hda codecs

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
        }
