If you want to be sure and have no xrun whatsoever a -rt kernel is definetly the better choice imho (don't have data to back that up though), especially because of the irq handler prios, which are not available on vanila kernels (maybe that has changed though). Seeting up the priorities right is crucial in setting up an audio system. I.e. i can run buffersizes of 32 or even 16 frames w/o xruns (except for application provoked ones), but of course the context switch overhead wastes quite a few cycles at these insane settings. But it's a good test case so one can be sure everything will be smooth at 64 frames. Have fun, Flo -- Palimm Palimm! http://tapas.affenbande.org
