[PD] sound with glitches

[altern]

actually he is using OSX 10.4.9 , i made a typo in first mail.

what you say is exactly what i thought, but we restarted the machine few 
times and it was always the same. he was not running anything else but 
pd. i also thought maybe it could be some driver problem, he has an 
external Edirol sound card he uses at home, here he was testing it with 
the built in sound card. maybe both drivers are present and PD goes funny?
