After a recent update, I lost all sound to my headphone jacks on an HP Pavilion dv6. Not sure where to begin. Does anyone have any ideas? The external speakers on my laptop work fine.

Add the alsa-daily PPA by running by the command:

sudo apt-add-repository ppa:ubuntu-audio-dev/alsa-daily

Update your packages list with:

sudo apt-get update

Then install the alsa-hda-dkms package:

sudo apt-get install alsa-hda-dkms

Reboot, and see the result! (This worked for me.)

Source: Sound from both headphones and speakers
