hello
After fresh install of kubuntu jaunty, sound seemed to work ok. Sadly, every time after some playing (say 1 minute) sound goes extremely... wrong. It's as it were trying to repeat itself and start again multiple times.
Search (google & forums) gives lots of output about sound not playing at all (for me works for short time after reboot) with intel sound cards (not my case as well). I though it's PulseAudio's fault, but kubu doesn't have it. I tried to install gnome-desktop, but that doesn't give new options in systemsettings/multimedia. BTW sound doesn't seem to work in gnome at all, but that doesn't worry me.
My card is:

It's Asus A6R laptop. I had to (as always with ubu) to mute external amplifier to have sound work at all.
What can I do to fix the sound?

Hi,
These guys (http://ubuntuforums.org/archive/index.php/t-1033041.html) (http://ubuntuforums.org/archive/index.php/t-1033041.html)recommend using OpenSound ( (http://ubuntuforums.org/archive/index.php/t-1033041.html)https://help.ubuntu.com/community/OpenSound) instead of ALSA on Ubuntu. Installed it 5 minutes ago, and still working :) Guess you should do some additional tinkering to get it work on KDE (I am _very_ newbie), but it well may be worth the effort.
Cheers,
