After the last zypper dup in Tumbleweed which mainly got me the latest kernel (see signature) my sound has gone. Pulseaudio is there, uses a lot of my cpu (22 to 60%). On my KDE desktop I have standard running kmail, chromium and skype (which of course is also not working)

Remembering from the past i played around with Yast, sound and alsaconf. alsactl kill and alsactl start did nothing.

A reboot with the second last kernel ( 3.14.0-22.g79de0a7-default) gave me my sound back and pulseaudio without cpu use.

Am I the only one with this problem? A bug report?

I've got a report bnc#871957, but I wasn't sure about whether it's really a kernel issue. https://bugzilla.novell.com/show_bug.cgi?id=871957

So, please double-check that it's a kernel regression. Switch between two kernels multiple times, and confirm that the problem is triggered only with the new kernel, and the old kernel always works as expected.

Switching the kernels multiple times I found that kernel 3.13.xxx always gave me sound. There was always sound when I came from a session with another kernel. At the second boot of the same 3.14 kernel sound was gone until I had a reboot with another kernel version. My question to you, does this phenomena also happen at your setup? Seems that the boot with another kernel version does leave something that helps to boot the system (with kernel 3.14) with sound at the next boot.

Once when it's confirmed, join the bug report there. Describe the working and broken kernel version numbers. Here, the git SHA ID embedded in the version string is important. Also, describe about your environment, especially attach the output of alsa-info.sh output (run it with --no-upload option).

If above reported behavior is much different from yours, does it still fit in the bug report?

Looking at the kernel git commits since the commit 79de0a7, the only significant change is about the update of XEN patches. If any, this is the likely culprit.

thanks,
