I'm trying to run Pd on a Linux distribution based on Debian (AVLinux).

My audio hardware (RME) has ALSA drivers and seems to work but I'm unable to test it - there is no sound from any application, selecting ALSA or Jack doesn't improve the situation..

Jack runs fine, I can see Pd and the system, connect them and everything looks good except that in the instant that I select Jack as audio device for Pd the canvas displays this error message.

Googling sends me to the source code and mail archives that are not accessible from here (China), so I'm clueless.

I'd very much appreciate any suggestions how to solve the problem. Even how to test audio hardware with a test signal or so.

Best
