Hi list,
I finally solved the problem: Upgrading to the newest versions of jack and pd in Debian Etch miraculously enabled me to start pd with jack. Pd with alsa alone still doesn't work - any explanations?
Thanks, Matthias

If your pd has been compiled with --enable-alsa you should be able to choose it from the menu Media->ALSA. Then do Startup->Save all settings.
I can choose it from that menu but I get "snd_pcm_hw_params_set_format: Invalid argument" and "tried but couldn't sync A/D/A audio I/O stuck... closing audio" messages. I get the same errors on 2 different computers which run pd fine otherwise.
I forgot to say that I use pd 0.39-1test1 and ALSA 1.0.13. The sampling rate switch on the UA-25 is at 44100 and so is the setting in pd's media-alsa menu.
Preferably you should use 48000 with USB soundcards (or any other samplerate that is a multiple of 1000.)
In fact I've noticed that I can achieve much lower latency (64x2 samples) since when I switched to 48000 with my UA-25.
But I didn't know that this setting was preferable.

Did you try the plughw:X devices in Pd's ALSA menu? And what about using OSS or jack?
Ciao
