I was just wondering if someone who is getting good performance with jack on 2.6.x could post their kernel config file here since I am getting bad levels of xruns in 2.6 where in 2.4.25 with the low latency patches applied, I get none. I am using Debian sid on an Athlon 2500+/ A7N8X-X motherboard with 512MB RAM.. SBLive! and onboard sound chip both give good performance in 2.4.25 but not with 2.6.3 James
