I have 2 Toshiba Satellite A135 laptops with SB450 HDA Audio. The sound did not work at all with Kubuntu 7.04 Feisty, but did work with Kubuntu 6.10 Edgy. I got the sound working by adding some parameters to the snd_hda_intel driver module. I did not update the ALSA drivers.
$ sudo vim /etc/modprobe.d/alsa-base Add the following line at the end of the file: options snd-hda-intel probe_mask=8 model=3stack I restarted the laptop after saving the changes to the /etc/modprobe.d /alsa-base file. Note: I had tried the snd-hda-intel options line with model=auto and that did not work for me. I tried the snd-hda-intel options line with model=auto without the probe_mask and it did not work for me. On the second laptop I downloaded and compiled the newer ALSA drivers and the 1.0.14rc4 drivers did not work for me. I got this workaround from https://bugs.launchpad.net/ubuntu/+source /linux-source-2.6.20/+bug/103379 -- last feisty update breaks sound: SB450 HDA Audio https://bugs.launchpad.net/bugs/88570 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
