dont know if you did this but the SGI fraq site will tell how to sync both outputs for 4 channel output....

Hi
Is there any special trick I have to do to make PD run with 4 channel output on an O2 (apart from recompiling)?? The machine is a 'standard' O2 with no extra sound hardware.
Right now I just get the same signal through both outputs (RCA LR and headphonephone jack).
TIA
