Found it: filename: /lib/modules/2.6.31-22-generic/kernel/sound/acore/snd.ko ^^^^^ In the original Ubuntu installation, this file is instead in: /lib/modules/2.6.31-22-generic/kernel/sound/core/snd.ko
("core" instead of "acore". See http://packages.ubuntu.com/karmic- updates/i386/linux-image-2.6.31-22-generic/filelist ) I don't know from where the "acore" file originates, but it is not in standard Ubuntu repositories, and it prevents your sound system from working. If the file is from a package, the output from "dpkg -S snd.ko" might help you - if the "acore" file shows up in the results. ** Changed in: alsa-driver (Ubuntu) Status: New => Invalid -- sound card not recognized https://bugs.launchpad.net/bugs/648400 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
