Public bug reported:
Audio only had "Dummy output" as output but after running:
$ echo "options snd-hda-intel model=generic" | sudo tee -a
/etc/modprobe.d/alsa-base.conf
$ echo "options snd-hda-intel dmic_detect=0" | sudo tee -a
/etc/modprobe.d/alsa-base.conf
$ echo "blacklist snd_soc_skl" | sudo tee -a /etc/modprobe.d/blacklist.conf
audio output changed to HDMI/Built-in-Audio however the sound is still
not working sound
