I’ll try to explain this as best as I can:
I have Pulse Audio Device Chooser installed on my SuSE 11.4 system and when i first started it up (after installing it quite some time ago) I had checked off “Start Applet on session login”. The problem is that whenever I boot up my computer, it will have more than one applet running (2 and sometimes 3 - depending on if I had closed the applet or not before shutting my system down). When I looked in the Preferences of the applet, the box, “Start Applet on session login” is now unchecked but as I said, it will be running there in the applet section of the “task bar”. What I have to do is to always remember to close that applet so that I won’t have multiple instances of it running when I boot up.
Is there an easy way to fix this? I just want it to be running only one instance and not more.
Well, this page re The Perfect Setup from the PulseAudio website may explain the status of the P/A “Install Utilities”, in particular this: “The two utilities PulseAudio Manager and PulseAudio Device Chooser are obsolete and should not be used”.
I have uninstalled Pulse Audio Device Chooser and that fixed my problem. I was kinda hoping that I wouldn’t have to do it that way, but since it is obsolete and should not be used, then I’ll not use it.
Thanks.
Probably you are running KDE? This is a well known phenomenon, multiple icons all pointing at the same padevchooser. Happens all the time.
In my experience in KDE it never caused an issue, I just closed down all but one and kept going. However sound management in KDE with PA was always clunky.
I found a lot of benefits of moving from KDE to Gnome with respect to multimedia. Pulseaudio was written with Gnome in mind, it works much more happily there. Consistently only one icon and the sound system is much more precise. I’m now in Gnome and would not go back to KDE given my current requirements.
Next time my son-in-law installs Ubuntu on his computer, I’ll go and play around with it to get acquainted with where everything is. Meanwhile, I have the Pulse Audio Volume Control app icon on my desktop for when I need it.
Thanks for the reply. 
Pulse Audio Volume Control is a useful utility to have available. Particularly useful if you lose the KDE Phonon and KMix support for P/A, as I did recently with KDE 4.6.5 update on Tumbleweed and P/A still working.
Glad you sorted it out.
