[SOLVED] Notebook Dummy output when there is no headset connected

I have a Alienware where the sound only works for the usb headset, jack or the internal notebook sound system doesn't work, it just displays a Dummy Output.

I have no idea how to configure it, but I tried some stuff I found online.

fuser -v /dev/snd/*

                     USER        PID ACCESS COMMAND
/dev/snd/controlC0:  joao       1672 F.... pulseaudio

lspci -knn|grep -iA2 audio

The content of /etc/modprobe.d/alsa-base.conf
However, without this file the results are the same.

Re: [SOLVED] Notebook Dummy output when there is no headset connected

An USB headset is it's own distinct sound card, so this isn't further surprising that works.

Remove the alsa-base.conf and install sof-firmware and reboot.
