I'm confused. jackstart -R -p512 -dalsa -dhw:0 -r44100 -p128 -n2 is 5.8 msec of latency and it can't be anything else. The issue is whether or not the system will perform reliably with these settings. I was misinterpreting your statements. You couldn't reliably run 128 frames with with RH9 and 2.4 kernel. Is that correct? Doh, I went and deleted the rest of your message--the improved low buffer size reliability is in a FC2/2.6 kernel? Have you done any tests with Ardour and JAMin at 128 frames? Well, those are encouraging improvements. With my setup, I'm getting decent enough reliability at 128 frames but when I record and mix, I turn it back to 1024. Under no circumstances can I tolerate a single xrun. ron __________________________________ Do you Yahoo!? Yahoo! Mail is new and improved - Check it out! http://promotions.yahoo.com/new_mail
