Is it possible to configure pulse audio to give me this? A simple possibility is not to load module-suspend-on-idle. Only when an audio devcie is suspended you won't get any data from it. I have thought of modifying module-suspend-on-idle in a way that it won't suspend a sink as long as a stream is connected to its monitor source. However, in the case of module-rtp-send this would be bad. Hmm, I'll probably add a new flag for streams. Something called "DONT_INHIBIT_AUTO_SUSPEND" or so which would then be set for RTP streams but not for yours. If that flag is enabled PA will ignore the stream when decideing whether a sink/source should be autosuspended.
