Solved with adjusted Dell work around. Zenith:
thanks for your link to the Dell workaround, which otherwise would be very hard to find. I did adjust the procedure for upgrading to kernel 2.6.24-21-generic Restore name of sound driver that old modem driver renamed: $ cd /lib/modules/2.6.24-21-generic/ubuntu/sound/alsa-driver/pci/hda $ sudo mv snd-hda-intel.ko.REPLACEDBYhsfmodem snd-hda-intel.ko Remove old sound drivers from kernel module directory: $ cd /lib/modules/2.6.24-21-generic/updates $ sudo rm snd-hda-intel.ko $ sudo rm snd-hda-codec.ko Rebuild initrd and reboot: $ sudo depmod -a $ sudo update-initramfs -u $ sudo reboot This brought back my sound working. Thanks a lot, Frank -- no sound after update to 2.6.24-21-generic https://bugs.launchpad.net/bugs/283790 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
