An update to this thread. I finally managed to open Pd and get sound out of it with the debian (jessie, I think...) image for odroid I installed on an SD card. I tried before with no luck, but after RalfD's suggestion, I logged in with ssh -XY ( I used to log in only with the -X flag) and it finally worked.

Thank you all for your tips, I guess this issue is solved (at least for me).

You might want to invoke your ssh client with the '-Y' option which
enables trusted forwarding.
Is the command ssh -XY or ssh -X -Y? Actually tried both but none worked...
