just for the sake of full understanding:
- why do you assume that audio-hardware and alsa drivers seem towork when
you are not able to playback from any application?
if the interface is not working there is a red blinking light on it. That's how I know when the Win driver gets corrupted once a year or so.
if the red light stops blinking when you boot into linux, then it has successfully loaded the needed firmware. so i assume that this isn't a problem here
- why do you assume that jack runs fine, when it doesn't work?
because it says "running" after I press start" and it displays a CPU load.
well, if i understand correctly, Pd (or anything else) using alsa says "running" as well (at least it doesn't show any problems) and it still "doesn't work".
oh, and a common pitfall: most RME devices hae a DSP-mixer on port, which is muted by default. (install and) start hdspmixer (if you have this card), this should most likely do the trick (make sure that the gains of the output matrix are set to something meaningful)
Thanks for the hint, I will have a look into the mixer.
i'm pretty sure that this is the problem...

Sorry my mail software doesn't do "reply to all" automatically.
(1) My mistake, there is a terminal command that initializes the card. Once this is done, the audio hardware works correctly in connection with Jack. I was able to test it now with the hydrogen drum machine.
HOWEVER Pd still generates the same error : The moment I select Jack as audio device it appears in the Jack connection panel (and I can connect it) but in the canvas of Pd prints the error message "audio I/O stuck... closing audio". The rest is silence.
I'm short of ideas... I cannot understand what "audio I/O stuck" means.
Best Jurgen

does it now work with Pd/ALSA ?
if you need jack, you have to provide more info: Pd's jack backend is far from perfect and there have been several attempts to make it work, which means, that different versions (and flavours) of Pd will behave differently. which one are you using?
Pd-vanilla at least will not startup a jackd automatically, so jackd has to be running before you start to Pd (or switch to jack). also note that switching audio-apis might work less than starting Pd with the correct API from the beginning. e.g. use something like "pd -jack -channels 8"

IOhannes,
I'm aware of the sequence of launching apps from OS X - I use Pd there with Jack and it works flawlessly. My mac is away for service, so I seriously needed to get started with Linux on another computer. This time I wanted to be very sure so I checked carefully - the moment Jack is selected as audio device in Pd it appears in Jack's connection panel. So I made sure that both in and out of Pd are connected to the 'system' and after that clicked in Pd on 'apply'. And it is working now :-) the sky is full of violins
I checked on using ALSA directly from Pd but it doesn't work - no feedback on the canvas and no output. This is like my audio hardware under OS X which also doesn't work directly from Pd. So I didn't really expect it.
Thanks for your advice and time, very much appreciated.

cool that it works now. (it was probably as simple as not having DSP turned on while switching to jack)

weird. i've been using all varieties of rme hardware on Pd and usually i don't(!) use jack but plain alsa.
