Just a follow up, Pd by default had imx-hdmi-soc (hardware) selected as an input and output audio device. Changing it to vt1613-audio (hardware) solved the problem and now I do have audio. How can I set this as a default? Every time I open Pd, I have to go to Audio Settings to change this.

There's something else that seems a bit strange to me (according to my very limited linux experience), in /etc/security/ there's a limits.d directory but there's nothing in that directory. Shouldn't there be something like a "90-realtime-base.conf" file includint the following lines:
@realtime   -   rtprio    99
@realtime   -   memlock unlimited

Should I create it?

Super, it worked! Though, I tried to open the Test audio and midi patch and the Pd window was gone. I stopped the session with ^C and started it again, opened a new window and put an [osc~ 440] connected to [dac~], turned the DSP on and nothing comes out of the headphones, plus I get this in the terminal:

snd_pcm_open (input): No such file or directory
snd_pcm_open (output): Invalid argument
snd_pcm_open (input): No such file or directory
snd_pcm_open (output): Invalid argument

More help?

Pd doesn't know where to display its GUI.

Depends on what you want. You can use X11 forwarding (ssh -X) in order
to display Pd's windows on your local machine. Or you can run an X
session on your Udoo and connect to your Udoo with VNC.
