[linux-audio-user] delta 44 con'd....getting rid of xruns??

Hello, I couldn't get the card to work using straight ALSA output from xmms, but firing up Jack with qjackctl got everything working. However, I am getting xruns (/glitches) when I do things as simple as switching windows...the output from qjackctl follows at end. What config do I need to adjust?
