Comment 480 for bug 1958019

Cameron,

I already have x1 nano, running fedora 34 with sway.

modifying modprobe with:

options snd-intel-dspcfg dsp_driver=1
options snd-hda-intel model=thinkpad

enables audio out, but mic is not working and audio out is horrible with constant static in background.

I will gladly contribute in reverse engineering, but do not really have any prior knowledge in that regrade.

Currently holding RHCE and done lot of tinkering with swaywm/i3wm hope it helps.

Thanks,
Kind Regards, George.
