Hey, I found out what caused my Problem. I used a Matrox G450 PCI graphic card (using matroxfb and fbdev for X11) . As soon as I tried a different graphic card (a ATI Rage 128 AGP - using no fb but ati for X11) the problem was gone. With or without the low-latency I don't have any dropout now even with very high load (up to 10). I have not yet tried if using a different matrox driver solves the problem. As soon as I find out, I let you know. Much thanks to Benno Senoner whose Howto(http://mstation.org/lowlatency.html) brought me on the right track!!

Thanx for the tip, but with the Matrox card neither the patch for 2.4.18 nor the 2.5.6 (low-latency patch included) solved the problem. > > > audio playback stutters on my system.
