Practically, it is more complex than the above since the desktop
motherboard can have 3 , 5 or 6 audio jacks at rear panel

since those hda codecs only have 8 channels instead of 10

Enable Independent HP on a 6stack model should decrease
spec->mult_out.max_channels from 8 to 6 for subdevice 0

For 5 jacks model , the driver need to retask blue jack as side only
when independent HP switch is off

To support 8 channels for a 3stack model need to retask the front HP as side
