<pre>Hi all
Johnny-come-lately I am . . .
I've experienced this problem since 0.43 (vanilla and extended), I
believe, but I haven't really investigated it, because it didn't happen
that often and I wasn't able to reliably reproduce it. Now I figured out
a way to reliably reproduce it. It seems the likeliness is related to
jackd's latency settings. The shorter the latency, the likelier is pd
going to freeze. With a setting of 128 frames/period and 2
periods/buffer, I can reliably freeze pd by turning DSP off and on.
The problem seems related to the fact that switching DSP also switches
the jack client on and off. I think the preferred way would be to be
able to switch DSP on/off independently from switching audio back-end
on/off.
@Miller
Are you still planning to seperate dsp switching from audio backe-end
switching for 0.44?

<pre>Hello,
I'm using pd-extended 0.43.4, installed via Hans-Cristoph Steiner ppa.
I'm using this version because I can't install the stable version in
Ubuntu 12.04.
The problem is, when I start pd with Jack in -rt mode or wherever
mode, if I turn on dsp, they work well, but if I turn off, and try to
turn on yet dsp, pd-extended freeze...
Closing Qjackctl (after some time ubuntu can close that)
pd-extended returns to work, and I can use on alsa directly
sucessfull..
Someone knows where I can comunicate this bug to the developers? Is
here the place?
Thanks a lot!
