here is a solution for that chipset, that worked on Tribe 4 on a D630 for _Doc_, and worked on gusty beta on a D830 for me : sudo apt-get install module-assistant sudo m-a update sudo m-a prepare sudo m-a a-i alsa +reboot ( or restart alsa components) I had compiled Alsa version 1.0.15rc1 as described on https://wiki.ubuntu.com/LaptopTestingTeam/DellLatitudeD830 , but it didn't work. maybe it's necessary to have that version of Alsa, and to do that trick to make it work..... At last i have sound !!! -- [gutsy] no sound on Dell Latitude D630/D830/Precision M4300/Vostro 1500/1700 pci id 8086:284b https://bugs.launchpad.net/bugs/131133 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
