hi Will, I do doubt that this is indeed relevant to your probs, but the symptoms are very much like something that bites me occasionally (and it always freaks me out until I remember). Do you have 'CPU Frequency scaling' enabled in your kernel(s)? I do, but I have scripts etc that are supposed to semi-automatically switch to the 'performance' governor whenever I'm doing audio related stuff. Occasionally, when things are getting experimental, I can finish up running jack etc with the 'ondemand' governor still active, which inevitably results in the sort of performance you're describing. Just a thought. cheers, Cal _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
