I have a dell laptop that runs ubuntu 10.04. The sound works fine when being played through internal speakers. However an external device such as earphones cannot play sound. How can I fix this problem? Please help
sudo add-apt-repository ppa:ubuntu-audio-dev/ppa sudo apt-get update sudo apt-get install linux-alsa-driver-modules-$(uname -r)
Try adding doing this: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).
