Today I made an online update (kernel was update too). Now - after the update - the boot splashscreen is gone. What’s pitty but not a real big problem. But now there is no sound anymore. What can I do? How do I do a rollback of this update? TIA, Ron.
A number of users have reported their sound broken by the kernel update.
I read one user managed to enable pulseAudio in Yast and got their sound back.
If that does not work for you, you could wait a week. The SuSE-GmbH packager for alsa has not yet released any new alsa versions for 2.6.27.23 kernel … if the past is a guide, then possibly next week we should see an update.
If you’re using KDE 4, click the KMix applet in the lower right panel and see if any channels in the mixer are muted.

If it is your grub/boot screen then as root in a console issue:
mkinitrd
See if that helps, also check that the update did not remove any vga=*****
settings you might have put in there, use Yast>System>bootloaer config.

I was the one with the post about pulsaudio but it didn’t work probably just a fluke???
What i have noticed is that after every boot the master in kmix is muted
/Geoff
My sound also disappeared after the update. I followed the advice here, to change the mixer settings, and voila… most channels were muted. Annoying, but an easy fix.
Absolute beginners: Click the loudspeaker icon, and then one more click on “mixer”. Thus you will see several channels, to play around with…

That id one problem I did not suffer, maybe because I got rid of all things
pulse related a long time ago, it was causing more problems than it ever
solved.
I just use plain old alsa and everything works exactly as it should do ( for
me )

Thanks to all.
ad sound: Mixer is the problem - two channels were muted.
ad splashscreen: I hope “mkinitrd” did the trick - a reboot will show.
ad sound: Mixer is the problem - two channels were muted. But after reboot the main channel is muted ever. Not very convinient. :X 
ad splashscreen: Kernel update changed the vga value.

For those with non-functioning sound as a result of the new 2.6.27.23 kernel, the SuSE-GmbH packager has now released the rpms for the update to 1.0.20 of alsa for the 2.6.27.23 kernel. Note this is on a special multimedia repository and not on the standard “update” repository.
There is guidance here for doing the update:
Alsa-update - openSUSE
Note one MUST send six zypper commands, being certain to pick the one’s specific to one’s openSUSE version. I recommend one optimize the alsa apps to be installed to match what one has on one’s PC already. … and also the second last command in the 3 command group should be specific to one’s kernel. Do NOT install multiple alsa-driver-kmp-<packages> … Only install the ONE that is applicable.
