Hi, I think you know this and probably do it right already, can't hurt to repeat it though. You have to run the sb-live with 48khz sampling frequency to achieve good performance. I haven't heard of this particular issue but I imagine it's possible since sb-live does internal resampling... More probable is perhaps that the card is faulty. /Robert On Tuesday 03 February 2004 04.37, Dave Phillips wrote: > Greetings: > > I've already written to the usual lists about this problem, but as yet > I've read no solution. > > During playback of audio in JACK apps (Snd, Ardour, SC3) the sound wil > often start out fine but after a few minutes it begins to distort in a > "zipping" fashion, like it's out of sync with itself.
