you could try before unload hda snd module and pass all its different variants, see Documentation/sound/alsa/HD-Audio-Models.txt

That was a good idea. It took some time, but the option "model=dell-md6" worked, as well as "model=dell-m23". SO I probably need to file a bug that the auto-recognition stopped working?

please provide alsa-info.sh output in working and nonworking case. so that alsa devs can see the diff.

thanks
