Just for kicks I tried: jackstart -R -d alsa -d hw:1 -r 48000 -p 512 and pd -jack -r 48000 -audiobuf 10 but now pd wont even start (but no errors from jack) [wade@transport wade]$ pd -jack -r 48000 -audiobuf 10 couldn't open MIDI input device 0 couldn't open MIDI output device 0 opened 0 MIDI input device(s) and 0 MIDI output device(s). Testing for Jack audio I/O stuck... closing audio

Segmentation fault [wade@transport wade]$ pd_gui: pd process exited

So, what up with that? Do I need to change the ownership of some pd or jack files? Now when I run jackd and pd as root it works (perhaps now because I specify the period for jack? sudo jackd -R -d alsa -d hw:1 -r 48000 -p 1024 jackd 0.90.1 sudo pd -jack -r 48000 -audiobuf 10

This worries me that nothing is certan in this pd-linux world... -theconfused
