I have the latest kernel! :S I cannot try a different sound card, but I think I've a good sound card... Every other program that uses sound card doesn't have this kind of issue... > The dmix plug-in won't get used by the OSS emulation.

I don't think it's a CPU overhead that causes the problem, because in gnome I've the CPU usage and during the emulation it stays about on 25% - 30% CPU Usage, I think that an Athlon64 3500+ with 2Gb DDR Ram is fully capable of emulating a 7Mhz 68000... :S Thank you again.
