With my recent discovery of the awesomeness that is SooperLooper, today is the day that I'm really trying in earnest to get a click and XRUN-free setup going with my Behringer UCA200 audio interface. For your reference, here is a screencap of my current qjackctl settings, along with the messages pane during startup:
http://holotone.net/qjackctl.png This setup seems to work great (no XRUNS) except for the fact that there's a consistent "clicking" noise when I push it too hard, say with a polyphonic synth; With a higher Frames/Period setting, these same clicks were the sound that always preceded an XRUN, so it seems odd to me that it's not triggering any in this setup. Highlighted in the messages pane, you'll see the error message that has me worried: "cannot lock down memory for RT thread (Cannot allocate memory)" A quick search on this yeilds info that it may be related to not running my apps as root, a problem I was under the impression that UbuntuStudio solved: http://ardour.org/node/1500 For what it's worth, it does appear that realtime is on, as the "RT" indicator flashes on and off periodically during operation. Any suggestions and / or ideas to get rid of these clicks and that strange error message? Thanks! ~holotone http://holotone.net/
