You have to determine which node 0x16 or 0x17 is your subwoofer and remove
the redundant speaker pin fixup

After remove the redundant internal speaker, 5.1 is only available after
you change the channel mode
Can alsactl restore the channel mode before pulseaudio probe the sound
cards ?
Auto mic select is not enabled when the notebook has mic jack and line in
jack , internl mic
As jack retasking is specific to snd-hda-intel and some multi cjannel ac97
codecs
It is not easy to force pulseaudio to stop all client connection, reprobe
the profiles on board audio after jack retasking
hdajackretask also perform the same function
stop pulseaudio and using dynamic reconfiguration/early patching
For those notebook with headphone spdif combo jack, it need a customised
iec958.conf and you can use headphone jack to make iec958 unavailable

state.plugged = no
