Unload the kernel module. On my laptop I had about an xrun per minute with
wifi on which went to xrun per 5sec when off and vanished when I unloaded
the wifi kernel module.
Also, just checking: Are you using the stock xubunu kernel? There is a
drop in lowlatency kernel available from the repos.
With regards to ONDEMAND/ Performance, ondemand give xruns up to 10ms
latency. (others I have talked to have reported similar experience) Even
running my cpu locked to 800mhz does much better (with userspace) I don't
have a problem here with performance, but if it makes things too hot for
your machine, set userspace and set your speed a little less than full
Ubuntu certified means works with the desktop. nothing more. No one checks
low latency audio on any of these things. (in your case it sounds like not
even normal audio)
