Expect : sound from speaker
Instead, obtain : no sound.
Tried various configuration of /etc/modprobe.d/alsa-conf with :
options snd-hda-intel model=XXXX and
options snd-intel-dspcfg dsp_driver=3 or 1
and systematic reboot.
Either I get dummy output, or I get proper output detection, alsamixer
and pavucontrol seems 100% ok, but no sound comes from the speakers.
I'm under a dualboot with Windows 10, BIOS fast boot disabled.
