I have not been able to run Jack now for months, but 3 months ago, when I was running Jack daily, I had my system on an ext3 drive and audio going to a reiserfs drive, and with my HDSP 9652 I never once saw an xrun at any latency setting of 256 or above. I might periodically get one at 128 and would get a few more at 64. All of that under KDE using RH 8. Actually, I have run Jack over this period, but only using the on-board sound chip, so that's pretty useless to me for anything other than looking at GUI interfaces, but with that driver (snd-via82xx) I did see xruns. Why did I not see xruns with the HDSP 9652? Mark
