Audio jack not working properly in Ubuntu

Audio jack not working properly in Ubuntu

The audio jack on the front panel of my HP TouchSmart IQ770 is not working correctly in Ubuntu (9.10 and 8.04). When I connect a headphone or a speaker to the jack, Ubuntu plays sound in both speakers - the default integrated speakers and the newly connected device. Vista mutes the integrated speaker and switches to the connected device, which is the behavior I'm looking for. This is not a 9.10 specific issue because I had the same issue with 8.04 too (and I couldn't solve it then).

"After hours of Googling and dozens or reboots, I got it working with the help of this post in ubuntu forums.

The solution is simple: add the following line to the /etc/modprobe.d/alsa-base.conf and reboot the machine.

options snd-hda-intel model=6stack

That line originally contained power_save, power_save_controller, position_fix and probe_mask variables along with the model variable that was set to auto. Sound did not work when I retained existing values for other variables and set model=6stack. I had to strip them off to get it working.

Hope this helps someone."
