"Device or resource busy" errors normally occur, when the sound
device is, well, busy i.e. there is nother application using the
soundcard. Check with "fuser /dev/snd/pcmC0D0c" or similar.

With Pd however a lot of people have problems using the RME cards
directly. You may be luckier if you use Pd over Jack. Otherwise try to
not use Pd's default device hw:0 when starting Pd but maybe use
plughw:0 first or define a device in your ~/.asoundrc, that matches
your favourite setup. Pd 0.37.1test6 now has the "-alsaadd" option to
let you specify arbitrary PCM names.
