Dummy audio output and no sound card detected by ALSA on Thinkpad T14s Gen 2
Closed, ResolvedPublic

Description

This is technically a duplicate of T9503, however I am on different hardware and have sof-firmware installed. I only have a dummy output option and no microphone option.
alsamixer reveals no options to remedy this, however the logs lead to me to believe that, althrough the firmware is working correctly, something else with ALSA may not be.
Audio on this device works without issue and out of the box on Ubuntu 21.04. Installing v1.9 from sof-bin, as suggested by T9538, fixes this isuse.

First of all, dmesg | grep snd:

[   44.052541] snd_hda_intel 0000:00:1f.3: DSP detected with PCI class/subclass/prog-if info 0x040380
[   44.052547] snd_hda_intel 0000:00:1f.3: Digital mics found on Skylake+ platform, using SOF driver
