this is a weird one for anyone using pda on gumstix verdex pro.

If i open a patch containing an adc~ directly connected to a dac~ on the gumstix with -nogui it sounds fine and audio passes through.
If I add a delwrite~ and delread~ into the audio path (i.e. adc into delwrite~ and delread~ into dac~) and open it with -nogui the signal path becomes incredibly distorted. If i open the same patch with a gui then it sounds fine?
anyone come across this before?
