Hello, thank you for taking the time to report this bug. Could you please try installing the 'linux-backports-modules-alsa-karmic-generic' package and reboot. After rebooting, double check your mixer settings as they may become muted in the process.

Don't know if that will fix your problem, but it won't hurt. Let me know if it works.

I installed all update, rebooted and now work!

Setting this to linux-backports-modules to register yet another sound device that is fixed by this.
