[alsa-devel] Subwoofers aren't working on ALC298 (Lenovo Yoga C930 Laptop)

Hi David,

Thanks very much for helping me look into this.

I just tried an Ubuntu live USB disk. I can't get subwoofers to 
work
there, either.

I don't see any option for that in pavucontrol on Ubuntu.

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?

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,
