i think it's from jack setup
search for jack issues with your specific hardware.
i mean what mac do you use ,
jack version is important too
Well, I've been posting on the jack mailing list too, and some people there mention that Pd is known to have a poor Jack support...
I also get clicks with Audacity, but someone mentioned that Audacity too is known to have a poor Jack support. Someone suggested that I use Pd with ALSA and use an alsa-jack-bridge to send the audio to my firewire sound card. I'll give that a shot and see what happens.
BTW, I have Jack 1.9.8

Just an addition to this, it shouldn't be pd's problem as I tried jack with audacity and got drop outs there as well. I'd be grateful to any help..

Forgot to mention that whenever I move a window around, open a subpatch, swich between applications while the audio is running, the sound stops till I stop which ever action.
Also I'm running $ jackd -d firewire -d hw:NVidia (forgot to write hw: in the first email)

Coming back to a previous thread I started, having compiled pd with jack, having done the realtime scheduling in jack, opening pd with '-jack' and '-rt' I still get some audio drop outs. The sound actually stops for a few ms, or even about a second, then comes back.
From the previous thread I was told that probably jack is waiting for samples that pd doesn't provide at certain moments. I went through jack's manual, but it is a manual for programmers and I'm not one, so I didn't make much of it.
The only thing I found in jack's FAQ is a question about audio with jack on a macbook (I'm on a macbook with ubuntu) that mentions a drivers problem that distorts the output http://jackaudio.org/macbook_distortion
but my output is not distorted...
I also tried to start up jack like this $ jackd -d firewire -d NVidia
but it really didn't make any difference (why should it? it uses the same sound card with or without  '-d NVidia'). Also used QjackCtl to change the block size, but also didn't work.
Dunno if this message in jack's terminal says something about the situation:
JackEngine::XRun: client = pure_data_0 was not run: state = 2
JackAudioDriver::ProcessGraphAsyncMaster: Process error

It appears whenever I open pd with '-jack'
I'm on a macbook 5,2 with ubuntu 12.04 and pd-0.45-4
Can anyone help?
