found something that would proofable trigger it). First there are a few
clicks and pops, then it becomes more "dense" and soon it sounds like
some high frequent crackling. (dropped frames i suppose, lots of them).
This lasts till jackd reports an x-run, and that's where it stops
abruptly. (So there are situations when xruns become your friend :-) )
BTW, any idea how i could get more "run-time" info on what happens in my
machine when this crackling starts? Is there a way to "see" irq activity?
The symptoms of your problem remind me of what I experienced with full
duplex operation on a SB Live (i.e., recording and playing back at the
same time). Are you using it in full duplex mode? I seem to remember
this having something to do with the record and playback buffers
drifting out of sync. I'm not sure it was ever solved though. It was
quite a while ago when I was playing with this stuff. Cheers.
