I have a similar (the same?) problem with pd 0.39-2 in xubuntu. When I move windows I get alot of audio dropouts (even in very simple patches). I don't get any xruns and the cpu load is ok.
Yes, I should have mentioned that both of those are also ok with me.
What I do get is alot of DIO errors. The audio works fine when i run GEM in fullscreen.
Ooh, haven't looked for those.
does upgrading your kernel to to 2.6.18 (optionally -rtN) help?
The vanilla kernel that I patched is 2.6.18. The default ubuntu kernel is 2.6.15. I'm not sure what you mean by -rtN? I run pd with -rt, should I be adding an integer, or are you talking about a kernel compilation option? I turned on full pre-emption, of course.
