Since the past few days, however, I'm seeing a > host of xruns and buzzes and drop notes. After (quite!) a bit of trial and error, I figured out how to make the realtime warning go away. Here's the new end of the /etc/security/limits.conf file: |@audio hard rtprio 50 @audio soft rtprio 30 @audio - rtprio 100 @audio - memlock unlimited @audio - nice -19 # End of file Not sure whether the 3 rtprio entries are necessary (result of copy pasting from different howtos on the net...!). message no longer appears. I look forward to better solutions. But the xruns remained... until I found the culprit: qjackctl was spiking CPU. Was about to complain to Rui, then found the source - it was a python script that I had edited a few days ago... and was spewing out dozens of warnings per second. Auto-launched from qjackctl, so the message window was clogging up, and therefore the spikes..! Closed the message window, and xruns dissappear. On a side note, I now have ~5.2 ms latency on an old Celeron laptop, with the vanilla kernel...! Linuxsampler + jackdmp has turned out to be a rather stable combination. Am getting down to building a proper realtime kernel, now....
