Ooops I have misleaded you with PinConfigOverride that's for all the Macs, dont look for it anymore.

Looking at your alsa-info, this is your Bass Speaker Playback Switch. It is in current Power setting=D3 and actual=D3. It should become D0 to be turned on.
Not sure if you can do this via alsamixer -c0 ?(or whatever number is your card). there is also a way with hda-verb (make sure you have hda-verb installed (from ftp://ftp.alsa-project.org/pub/tools/alsa-tools-1.1.7.tar.bz2 alsa-tools ftp://ftp.alsa-project.org/pub/tools/alsa-tools-1.1.7.tar.bz2 ?))
According to https://www.kernel.org/doc/html/v4.16/sound/hd-audio/notes.html
power_save_node (bool) advanced power management for each widget, controlling the power sate (D0/D3) of each widget node depending on the actual pin and stream states could be a permanent more elegant solution in a hda-jack-retask.fw patch, but no idea how it should look for that widget exactly, Takashi can suggest.
You can try for now enabling that Power: setting=D0, actual=D0 if that will help you probably:
Documentation is at: https://www.intel.com/content/dam/www/public/us/en/documents/product-specifi... Page 153 is of your interest. 0x705 is the SET verb, 0x00 should be fully on D0 state # sudo hda-verb /dev/snd/hwC0D0 0x17 0x705 0x00 you can get the value from the codec back: # sudo hda-verb /dev/snd/hwC0D0 0x17 0xf05 0x00
Hope that helps, if that solves the solution as a dirty thing you can put that hda-verb command in your /etc/rc.local (depending on the distro rc.local maybe deadend).

Hi David,
Thanks very much for helping me look into this.
Have you tried any other distribution, something more normal like latest Fedora or Ubuntu ? Does the subwoofers work there ?
I just tried an Ubuntu live USB disk. I can't get subwoofers to work there, either.
If you run Ubuntu/Fedora you can check the sound settings and pavucontrol there is selection of speakers usually 2.1 5.1... try those ?
I don't see any option for that in pavucontrol on Ubuntu.
And you have to make sure those [pincfgs] match with your Windows10 registry of the driver's PinConfigOverride.
Awesome. How can I find these settings? I checked in regedit and searched for `pinconfigoverride` and `pincfg`, but nothing's coming up. I also grepped all the driver files for those expressions, but nothing's coming up there, either. Do you know if these settings are called something else?
You happen to have Windows running on that machine and can extract the pinconfigoverride or have .ini of the driver? I can help you compare those.
Yep, I have the Windows 10 driver files, but there is no .ini file, as far as I can tell. There are lots of text files that look like they could be configuration files of some sort. Which one(s) should I be looking for?
Best,
Jonathan
