It isn't that I can't install a new kernel, just easier to keep packaged
versions on machines, so I don't have to track any security updates in
the kernels..
But figured there SHOULD be some way to debug how codecs are detected,
wanted to understand HOW the internals work better, and hopefully
without crawling through kernel sources..
Thinking there should be some user land tools to replicate how the
kernel internals identify codec related things, rather than just
randomly trying alsa module configuration items.

Appreciate the response, but running the 16.04 LTE with the hwe
kernel, which should have updated support. I would expect that at
least an older codec should be supported on the board, highly doubt a
completely new sound card shipset would be used.
How do I try to resolve this WITHOUT going to a 5.6 kernel?
The best is to ask your distro. It's a distro kernel, and we have no
idea what's missing and what's fixed, after all.
But, if you can just test 5.6.y kernel while keeping the rest of your
system, and it still shows the same problem, then it becomes more
interesting to us. Installing and testing a new kernel takes only a
couple of minutes. Any reason to hesitate to do it so much...?
thanks,

The 4.15.0 kernel was released in January 2018. Your computer was
first sold around May 2018 (at least where I'm from). It's hardly
surprising that some components in your computer aren't
supported. First try upgrading to a newer kernel (ideally 5.6)
before you try other steps to debug your issues.

Hi All,
Technically this probably should go to a support channnel, and not
a development list, but at my wits end.

I have been playing with settings in the modprobe directory for

options snd-hda-intel single_cmd=1
options snd-hda-intel probe_mask=1
options snd-hda-intel model=thinkpad
options snd-hda-intel position_fix=3
Have tried model=generic, and various other suggestions from
online, but at a loss. Don't see anything in:

Your ALSA information is located at

Can anyone point me to how to debug this further, or any way to
force detection of a proper codec for this model?
