Re: [FRUSTRATED] Missing Sound Codecs for Lenovo ThinkCentre M710e

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 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]) [   12.807521] snd_hda_intel 0000:00:1f.3: CORB reset timeout#1, CORBRP = 0
[   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 http://alsa-project.org/db/?f=7898b30139e9a91fecec22f3ee46049f33248b85

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