Hi It seems that I get quite stable performance by starting jack like this on my P4 2.4Ghz laptop with onboard i810: jackstart -R -v -d alsa -n 3 -p 256 -zt But what exactly does this translate to in terms of latency? Should I expect more? I get almost the same performance under 2.4.23 with Andrew Morton's low-latency patched and 2.6.2 with or without the mm-patch. -- peace, love & harmony Atte http://www.atte.dk
