--- Comment #10 from Andreas Boll andreas.boll.dev@gmail.com 2012-08-08 19:10:15 UTC --- Can you test it with kernel 3.5 and current mesa-git? There were streamout fixes for r700 in both kernel and mesa.
projectM-pulseaudio runs fine on my system.
Gallium 0.4 on AMD RV770 -- 2.1 Mesa 8.1-devel (git-be42a45) Kernel 3.5 (enables streamout for r700 by default) ColorTiling2D enabled
