hi list after a while pding on OSX i'm trying to switch to linux. compilation was ok, but when i start pd i get:

/dev/dsp (writeonly): Device or resource busy
/dev/dsp (readonly): No such device or address
error: failed to open MIDI ports; continuing without MIDI.
audio I/O stuck... closing audio and MIDI

i don't care about the MIDI part, cos i won't be using any, but i obviously want some audio ;~) i assume it might be something very easy to solve, but i'm still a newbie here and i get lost with dev permissions etc. hints? r
