Yes, sure. And with pulse, that's trivial: *If* such a daemon really is 
running and disturbing, it's easy to silence via pavucontrol.

Please check the scenario I outlined again (copied again below).

That was a real case, of a friend who dropped pulseaudio, because that 
wasn't workable.
I have a similar setup, but no problem, because I have a dedicated HTPC 
machine that is always running, and always with the same user account.

If you don't know mpd, please check it out. The whole idea is that I can 
control from several clients, but the playback is done by the server. 
And it's *really* cool, esp. combined with an Android tablet.
