Thank you Stefan Bader and Stuart Johnson! I followed your advise and furthermore did a complete reinstall of my test install of Ubuntu 9.10 Karmic. What you described seemed indeed to be the problem, because if I change power_save in /etc/modprobe.d/alsa-base.conf to 0 the bug is not occurring any more.
