How to set up audio redirection

There are currently two ways of using audio redirection on xrdp.

Using Pipewire

See https://github.com/neutrinolabs/pipewire-module-xrdp

On debian/ubuntu it is also available through apt:

sudo apt install pipewire-module-xrdp

If it doesn't seem to work after a restart, just make sure your window manager properly launches /usr/libexec/pipewire-module-xrdp/load_pw_modules.sh when starting (using a mechanism specific to your window manager).

Using pulseaudio
