Output of "pactl list sinks"

If this module is loaded, HDMI output (stereo and 5.1) is not working when I
start a player like VLC or Rhythmbox. I have to fiddle with the output
configuration of Pulseaudio (e.g., changing from 5.1 to stereo and back) or
with the input configuration of my receiver (e.g., re-selecting the input
source my computer is connected to) to hear sound.

If I pause and continue the playback, sound is still fine. If I quit the player
so that no stream is playing at all and start it again, I have to perform the
above procedure again.

Unloading the module suspend-on-idle solves this problem whereas loading the
module produces the problem reproducibly.

Hardware: Intel Sandy Bridge cpu & mainboard with onboard video card with HDMI
output (see attached file sink-list.txt). My receiver is a Denon AVR-1910.

Software: Pulseaudio 1.0 from Ubuntu 11.10 x64 (package version 1:1.0-0ubuntu3)

I had already filed a bug in the Ubuntu bug tracker:
