I've tried
$ 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
and
$ sudo apt-get install --reinstall alsa-base pulseaudio
$ sudo alsa force-reload
and
$ sudo apt purge timidity-daemon
and
added snd_hda_intel.dmic_detect=0 in /etc/default/grub with no luck
Xubuntu detects the HDMI sound hardware and the mic.
Here is the output for some commands about the system, hardware and modules.
