As for the upmixing feature, I wonder why no one complain about sending
left
channel to the center and right channel to subwoofer
Well, maybe because usually you set up 5.1 properly when you have such systems, then upmixing right in the backend, not in the driver.
I have Creative 4.1 speakers which only has green and black jacks.
Refer to commit d29240ce57d96db7300360d1e6f18357810a5c2b
hda-intel driver unconditionally assigns the stream to multiple output pins in copy-front mode
I can hear the stereo in all 4 jacks in rear panel because of copy-front mode even in OSS emulation
This is why ad1988 still can use "Headphone Playback Volume" at DAC0 when switch off "independent Headphone"f
