alternate-sample-rate is post-1.1 I think (and I did not get it to work)

I think this is intended behaviour
see pulseaudio --exit-idle-time=SECS

or check /etc/pulse/daemon.conf:
; allow-exit = yes
; exit-idle-time = 20

on an embedded system, I'd rather use --system

PulseAudio tries to allocate 64MB per default I think, maybe too much; can 
be configured...
