It does munch up about 80% of my CPU, though. Are you sure you don't have anything like profiling enabled in your kernel? The GF1 (/dev/dsp0) output does need some extra processing (in gus_copy_from_user() in gus_wave.c) which the CS4231 doesn't need. Anyway, I do have to improve the patch a bit, because currently it does break L...x compatibility (you only care when you're resubmitting the patches to Hannu, the VoxWare maintainer) --- Alain
