Hi everyone!

I have problem with my sound blaster 5.1. Like u probably know I use ALSA and Pulsaudio in my desktop. Now I try describe the problem. When I listen radio or music in Rythmbox I have the same error. Error occurs randomly. My syslog:

and the my gdm, gui restart automatic. I will help and translate this: "This is probably a bug in the ALSA driver 'snd_emu10k1 ". Please report the issue to the ALSA developers services." What can I do ? Sorry for my language.

Best regards!
