1) I checked and I have direct rendering: yes.
2) I tried -rt and it makes no difference. I also tried changing -audiobuf 
and -blocksize (up and down) and I still get frequent audio pops. 
3) I haven't tried using 2 pds in parallel one for sound one for graphics. 
But the sound is only playback of an existing file (no processing) through 
[sfplay] so my intuition is that it doesn't make much sense in terms of 
computation load.
4) I don't work with Jack bacause I get x_run errors and added noise. 

any other ideas?
