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?
That's a question for the people over at Ubuntu. Upstream people like
the ones on this mailing list generally don't do distribution support.
Most of them have no idea what Ubuntu did to their kernel, and which
updates they did and didn't pull into their tree. It's not their job to
try and debug problems they could well have already solved a year ago;
that's just a waste of developers' time. If Ubuntu decides to patch up
and ship an outdated kernel, they get to take responsibility for it.
Meanwhile, my well-meant advice stands: try an up-to-date kernel. If the
problem persists, you can file a bug and get a developers' attention. If
the problem goes away but you really really want to keep running
Ubuntu's 4.15.0 kernel branch, you can persuade Ubuntu to pull relevant
fixes into their 4.15.0 branch and release an update.

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 Also
with no effect.. current settings are..
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:

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