Describe the issue you are having.

I would like to run digimode hamradio software like wsjt-x or fldigi in UserLand. However, these applications require full duplex audio in order to communicate with the radio. All possible solutions I found are related to audio playback, but not recording / sound input. Possible solutions could be a full duplex pulseaudio client for android (could not find one), an android implementation of jack2 netjack, or maybe this: https://github.com/twaik/pulseaudio-sles-ndk

Describe how your task behaves in a regular Linux environment

I just choose the audio device(s) that I want to use either from within the software or linux.

First question - do you have pulseaudio working (output only) using VcXsrv?

First question - do you have pulseaudio working (output only) using VcXsrv?

I am not using VcXsrv because all my machines are running Linux. However I can connect audio from Debian/LXDE on Userland to my Linux desktop with PULSE_SERVER="xxx.xxx.xxx.xxx:4713" (xxx being the desktops IP). This even works in duplex mode. With Audacity running in Userland I can both record and play from the remote desktop. Probably the simplest solution would be an Android pulseaudio server, but I cannot find anything with duplex capability - only playback.
