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.

After a little testing today the -jack flag works fine using the earlier
the Pd-0.40.3-extended-20080210-debian-stable-i386.deb build. So it must
be something in the bugfix that messes up using external cards ...
