"RME" is a bit vague.
which hardware are you using?
for multi/digiface you will have to load a (special?) firmware to the 
device before you can use it.

which one?


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?
- why do you assume that jack runs fine, when it 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)
