I don't think so. If an sound app is swapped out or another app is doing intensive disk IO we could observe - hear - the difference. aoss app can even stop and crash, some native ALSA apps too. Maybe they are badly designed. Generally if the kernel know about time critical app it can schedule them at appropriate time. And this could be done only by kernel. Some apps colud run slower and it should be acceptable - compilation or file copying for example. > Personally, I am very satisfied with the dmix performance with recent > fixes.

I have low latency option on and some disk io optimiztions turned on too but can easily observe buffer underrun and ALSA aoss app failure by doing high CPU and disk IO operation - opening 500MB tar.gz file for example.
