Got sound from Pd in UserLAnd TSVNC Xfce4 Debian Bullseye via Pulseaudio RTP VLC, all installed via f-Droid on an Android tablet. Using xvkbd to be able to type. Not yet tried patching, I expect it to be nightmarish...

Had to set latency really high and increase block size in Pd Portaudio settings to get a clean sound.
