[PD] Pd / Purr-Data and Ausus Tinkerboard - analog sound card does not show up (alsa)

VLC was set to "automatic". That means it was most likely using Pulse audio
(which is working fine for VLC but not for Pd).
Then I set it to ALSA. In this case I had to use "USB Audio, USB Audio #2" in
order to get any sound output.
In Purr Data or Pd I can set only "USB Audio" but not "USB Audio, USB Audio
#2".
Setting USB Audio to 4 channels results in the error that I mentioned in my
previous mail:
"ALSA: set output channels to 2"
So it looks like it needs to be set to "USB Audio, USB Audio #2" which is a
sub device of "USB Audio" that is neither available in Pd nor in PurrData.
Any idea how to make it available?
I already tried installing Jack and see if I can get to it this way but didn't
succeed because of some installing errors (missing or wrong dependencies?).

Can you check the VLC preferences to see which audio backend it is using?
