Depends on the specific versions on your rPi, but try:

add 'snd_pcm_oss' to '/etc/modules' to make it work after reboot
'modprobe snd_pcm_oss' to make it work before rebooting

Coming back after a few days. adding 'snd_pcm_oss' to /etc/modules also did it. I don't need to launch Pd via aoss anymore, I launch it properly (/usr/local/bin/pd) and audio works fine. Thanks!

or try:

install 'alsa-oss' if you haven't already got it
run 'aoss pd' instead of 'pd'
