Crackling Audio In Renoise With Jack On Usb Interface

[rhowaldt]

@kaimerra

I am getting some crackling noise during playback in Renoise. This is only happening when using my USB audio interface through Jack and not my internal IntelHDA chip. I am not getting XRuns during these crackles. I don’t get the crackles in other audio apps(ardour, hydrogen, guitarix). I changed the USB cable and my headphones to make sure they weren’t culprit. I am out of ideas here. What could be causing this crackling noise?

Running:
renoise 2.6.1
Fedora 14
Jack 1.9.6

have you read this?
have you read this and tried changing window manager to Openbox?

if both answers are ‘no’, have you done a forum search?
