I found a solution of sorts. So in case someone else has the same issue ... I remapped the NoMachine microphone source to a new source - without changing any parameters. I also had to disable the suspend-on-idle module because otherwise the newly created remapped source would sometimes get suspended and I found no way to un-suspend it. Magic incantations: pacmd unload-nodule module-suspend-on-idle pacmd remap-source master=nx_voice_out.monitor source_name=Microphone I don't really understand why this works. The remapped source is just a renaming, since I didn't change any parameters of the master. I'd like a way to un-suspend a source after it has been suspended because of idle - pacmd suspend-source false - doesn't do it.
