Ok, I can give you some rpm commands to update your alsa. The problem with this approach (although it has a reasonable chance of success) is if you subsequently update your kernel version, it may break your sound, forcing you to update the alsa driver again.
As before, I note opensuse-11.1 with the original 2.6.27.7-9-default kernel . Please confirm that is still the case wrt the kernel. ie type: uname -aif your kernel is still the 2.6.27.7-9, then do the following (if it is NOT then stop now and advise):
1st remove that custom line from your /etc/modprobe.d/sound file.
Then with your pc connected to the internet, open a konsole/terminal and type ‘su’ (no quotes - enter root password when prompted) and copy and paste the following six commands, in sequence, one at a time, into that konsole/terminal and execute them:
zypper ar http://download.opensuse.org/repositories/multimedia:/libs/openSUSE_11.1/ multimedia
zypper install alsa alsa-docs libasound2
zypper rr multimedia
zypper ar http://download.opensuse.org/repositories/multimedia:/audio:/KMP/openSUSE_11.1/ multimedia
zypper install alsa-driver-kmp-default
zypper rr multimedia
then restart your PC, and test your sound/headphone. Be careful to check your mixer settings.
If that does not work, you could try again the model options for 1.0.20 of alsa in your /etc/modprobe.d/sound file, restarting alsa and restarting your mixer after each attempt.
If that does not work, then go on to the daily snapshots of alsa. You can do that with your pc connected to the internet, open a konsole/terminal and type ‘su’ (no quotes - enter root password when prompted) and copy and paste the following six commands, in sequence, one at a time, into that konsole/terminal and execute them:
zypper ar http://download.opensuse.org/repositories/multimedia:/audio:/snapshot/openSUSE_11.1/ multimedia
zypper install alsa alsa-utils alsa-tools alsa-firmware alsa-oss alsa-plugins alsa-plugins-pulse libasound2
zypper rr multimedia
zypper ar http://download.opensuse.org/repositories/multimedia:/audio:/KMP/openSUSE_11.1/ multimedia
zypper install alsa-driver-kmp-default
zypper rr multimedia
You may be told some are already installed. Proceed anyway, sending all commands. Then restart your PC, and test your sound/headphone. Be careful to check your mixer settings.
If that does not work, you could try again the model options for 1.0.20 of alsa in your /etc/modprobe.d/sound file, restarting alsa and restarting your mixer after each attempt.
Again, note those are for the original 2.6.27.7-9-default kernel and if you have changed your kernel version (which can easily happen with an openSUSE update) then the commands MUST be different.
Good luck.
