i have the glitchy sounds with jack. i'm running jackd -R -d alsa -p 128 -r 48000 & pd -rt -jack -audiobuf 128.

but in Media / Audio settings / dacblocksize is 64. i cannot change it? should i run jack in 64, cause i think pure data have a blocksize of 64 by default. so maybe i will save some cpu or have less glitch? not sure...

ok ... i did some changes to the sleepgrain of the scheduler ... i hope this works ... btw, for jack the audiobuf setting isn't used at all ... only the -p option for jack controls the behaviour ...

cheers ... tim
