I must have missed that change (I don't have much time for mucking about with kernel these days). > That might have been enough to cause a difference. > This is all configurable in the kernel, of course, but it now defaults > to 250Hz. That indeed might explain the noticeably poorer audio performance with SDL now. I still think some smarter code might help: I don't want to have force people to build their own kernels just to get reasonable performance. Cheers, Rich
