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.
Kernel: 4.15.0-91-generic #92~16.04.1-Ubuntu SMP
dmesg | grep snd
[ 12.656843] snd_hda_intel 0000:00:1f.3: bound 0000:00:02.0 (ops
i915_audio_component_bind_ops [i915])

[ 12.810429] snd_hda_intel 0000:00:1f.3: no codecs found!
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:

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?
