Ubuntu – Headphone jack not working

alsapulseaudio

I have a Dell Studio XPS 1647 and headphones do not work (though , internal speakers work like a charm) , I have dual boot Windows 7 and headphones work perfectly fine …

I also tried -adding in options snd-hda-intel model=eapd probe_mask=1 position_fix=1.

I've experienced this with Oneric Ocelot and the latest Precise Pangolin (LTS).

I've tried all these responses. Here is the ONLY way that worked for me (and it was remarkably quick... after spending hours on all the other suggestions!). Go into Terminal, and simply key this in:

$ alsactl restore

And that's that! :)
