For some time I been trying to get sound to work on this Dell as I have a few of them. I've been trying different things and I still can't get the output working from the mini-jack for sound on the Dell Optiplex 760, I get sound output on the built in PC speaker. Have anyone else come across this issues, or give some pointers where to start.
I've tried Ubuntu 10.10/11.04/11.10 - no results
I've added a ppa for pulseaudio and upgraded - no results
I've added some things to the blacklist for modules for internal PC sound - no changes
Any help or pointers would be greatly appreciated!
