Testing for audio playback

Just a heads up: I think that checking the status won't work with
pulseaudio running under 2007.2, since pulseaudio continuously sends a
stream of zeros to the sound card. I haven't tested it though.
(there is a pulseaudio configuration option for this.)
Also, I think having the applications disable suspend would be better
than letting some system-level daemon guess what the appropriate
behavior is.
Then audio activity and suspend wouldn't be coupled (eg: tangoGPS while
recording GPS tracks...). Also, applications already communicate with
the rest of the system, so there's probably a framework for such hooks
somewhere. For example, mediaplayer mutes/pauses when a phone call
comes in...
