I've never had any problem with sound on my Dell Laptop. Its a very standard Intel Sound-chip.

After upgrading from KDE 4.21 to 4.22 i lost sound. I rerun alsaconf but with no luck. Then i try Sound-settings in Yast-Hardware-Sound and then the sound come back, but after reboot its gone again.

I also try "rcalsasound restart" but then the volume-controll disapeare and still no sound.

Bug in KDE4.22?
