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:
