Summary: Ubuntu Hardy PD Jack problemos ...

Initial Comment:
Ok,

After upgrading to Ubuntu Hardy I tried pd with jack and everything seemingly 
was working.  Today I sat down to do some music using my external usb sound 
card (Edirol UA-25) and lo and behold Pd goes nuts.  All afternoon I have 
tracked down these issues using 
Pd-0.40.3-extended-20080408-debian-stable-i386.deb from the autobuilds.

- the -jack startup flag does not work

- if using the -jack startup flag, trying using the jack selection in Media 
does not work, you cannot make the jack connection to work

- starting pd without the -jack startup flag allows you to select jack from 
Media and make the connection

- trying to connect to jack (once again from the Media menu) if its controlling 
an EXTERNAL audio device immediately slows down X to about 5fps and causes 
Pulseaudio to stutter.  Everything is fine on killing pd.

As suggested by Hans, I tried a build before the recent jack bugfix patch 
(http://pure-data.svn.sourceforge.net/viewvc/pure-data/branches/pd-extended/v0-40/pd/src/s_audio_jack.c?view=log)
 and I am able to connect to the external card running jack ... but the startup 
flag does not work.
