options snd-hda-intel index=0 model=alc255-acer,dell-headset-multi
but after one of the latest updates, this method does not work. I found solution. Just replace the lines above with this:
options snd-hda-intel index=0 model=headset-mic,alc255-acer
and reboot. It helped me.
I just wanted to share the solution to the problem with the forum members :)
