And to think all I did to get my cheap USB sound card to work at

change buffer and period settings on QJackCtl's non-Advanced
settings tab.

That's on two different systems: one Intel i7, the other an AMD
Phenom 2. No tweaking deadline scheduler or scaling governor (for
the Intel, Phenom 2 has no such capability).

But I'm using Debian Testing + KXStudio, not ArchLinux or Ubuntu.
David, what desktop are you using?  LXDE?  Other?

XFCE. One difference that might affect your set up: My card only does
48000Hz max and has 2 stereo channels in and out.

That's very interesting.  This time around, XFCE gave me xruns which I couldn't eliminate, LXDE has been flawless.  Am running 48 kHz these days, it looks like I'd have to spend a good bit to get 96.
