Hi, I use the nouveau driver on archlinux since aprox. 1 year with a 7xxx card. The soundcard is the legendary maudio 1010l. I never had problems with xruns since I'm using nouveau. If you have specific tests to run on that system, I can perform them on the machine in a week or so (as soon as I'll be back from my holidays).
