Is there a module that can run a (configurable) shell command when

? Effectively, this would work exactly like a screen saver, just for
sound, not for the screen/input.

Ahh interesting. Yeah you could use this to know when PA is playing
sound. All you'd need is a simple dbus integration and you could write
your app accordingly completely separate of PA.
The other option is to get your hands dirty, write a module in PA and
use that.
I think other people may have posted similar modules in the past, but it
won't be too difficult to do it either way - module-suspend-on-idle will
have pretty much all the infrastructure you'd need.
Of course some apps misbehave (e.g. flash) and keep their streams around
even when they are not playing and thus may need some kind of special
handling here that you probably won't get via dbus or idle status.
Ah. That's why I said "an application plays a sound" not "a source is
connected". I have apps connected constantly, e.g. an mplayer on pause.
This is normal in my usecases, the speakers *must* turn off anyway.
If the dbus trick doesn't provide that, I can't use that. Does
module-suspend-on-idle handle this case? Can I hook up a shell command
there?

Do you have the URL of them, or at least remember some keywords to
search for?
