Yes! I am running XFCE and/or also have Gnome installed.

I will try xmonad ... is there an easy way to add it to config.scm so I can
F1 to choose it, and if not, where/how to I configure GuixSD's X to use it?

Otherwise, there is a pulseaudio jack sink that may work if I can be told
where to put it.

Thanks a bunch!
