I just want to clarify and say that the init script will gererally *not* 
be used under normal operation.

Pulseaudio has two modes, system and per-user. System mode would use the 
init script but is generally not recommended for standard desktops. 
Per-user mode is usually the way to go and should be the default on 
Ubunutu (as far as i know). This mode allows proper integration info the 
console-kit for knowing which user is active (e.g. if you loging > 1 
user at a time) and thus grants and denies access to the sound hardware 
as appropriate.

Well I presume you are using padevchooser. This should not be used. Use 
pavucontol. The whole point in pulseaudio is that you can change the 
source and sink *without* restaring the application!!

The fact that Ubuntu does not install pavucontrol and promote it's uses 
is IMO a mistake as without pavucontrol, the benefits of pulseaudio 
cannot be realised.

See my other reply about this. It's working well here now with the 
fedora patch. If it doesn't work on Ubuntu, you should poke them and ask 
them to include the patch.
