Are there any offical specificaion ?
So far most review only mention stereo speakers and subwoofer, the
service
guide only show how to replace two internal speakers
Service manual mentions "Dolby®-certified surround sound system with two built-in stereo
speakers and
one subwoofer supporting low-frequency effects"
so all additional channels what I'm hearing in Windows is emulated. I hope that it is clear now that my laptop has two internal speakers and one subwoofer.
You have to determine which node 0x16 or 0x17 is your subwoofer and remove the redundant speaker pin fixup
Thanks. I know how to help myself, but I expected it by default. I wonder

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
