Headset does not work on Ubuntu, but works on Windows and other distributions of Linux.
I have HP Pavilion DV6
A friend of mine has a dv6-2153el, and he solved this problem running
echo "options snd-hda-intel model=hp-dv5" | sudo tee /etc/modprobe.d/snd-hda-intel.conf
then rebooting.
If this doesn't work for you, you can undo with
rm /etc/modprobe.d/snd-hda-intel.conf
It's a long shot but, try unmuting them from the alsamixer
(just type alsamixer
in the terminal to run it).
pulseaudio --check
,pulseaudio --dump-conf
,amixer -c 0
,pacmd dump-volumes
andpactl info
