Ubuntu Gnome 16.10, Dell Latitude 3540

With 16.10, when you insert the headphone jack, it senses and a dialog comes up, to which I selected "Headphones", but no sound comes.

Sound is fine on speakers. Sound is fine on headphones under windows.

I tried alsamixer, and it correctly shows headphones at 00,100, and speakers at MM.

pavucontrol shows sound coming from VLC player and headphone output at 100%

$ lspci | grep Audio
00:1b.0 Audio device: Intel Corporation 8 Series HD Audio Controller (rev 04)

Before I start meddling with conf files in alsa-mixer, does anyone have a clue on what could be going wrong? Everything was fine in 16.04.


Try to run this on the terminal:

gksudo gedit /etc/modprobe.d/alsa-base.conf

and add the following:

# Keep snd-pcsp from being loaded as first soundcard
options snd-pcsp index=-2
alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
options snd-hda-intel model=dell-headset-dock

Unplug and plug your headphones and restart if necessary. I hope that helps. Good luck!
