Hi, I posted our problem on the toshiba-linux mailing list and got the following reply:
The problem isn't with the 2.6.22 kernel, it's actually with the 2.6.23kernel and the Ubuntu team has backported the change to 2.6.22. A vanilla 2.6.22 kernel with a DSDT patch and the latest alsa drivers works just fine whereas the 2.6.23 kernel or the Ubuntu 2.6.22kernel don't give sound regardless of alsa version. I haven't checked the patches that were applied to the Ubuntu kernel but, when I get the chance I'll see if I can figure out what the problematic patch is. I'll keep you up-to-date about this. @ arkara: You don't have to get Feisty if you're already on an installed Gutsy. Just change/add the feisty repositories (edit /etc/apt/sources.list, all gutsy > feisty) and install the 2.6.20-16-generic kernel. How to fix and apply the DSDT: please look at the ubuntuforums.org and/or google, I think the procedere should be described there en detail. If you have some problems please post it there. I suggest this thread should be up to the gutsy kernel problem. -- toshiba p100 series dsdt acpi error no sound, works with acpi turned off. https://bugs.launchpad.net/bugs/136469 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
