There I was, happily using Amarok 1.4.3 on Ubuntu 6.1 Gnome using KDE 3.55.  I installed some stuff, who knows what, and now I get the "No suitable demux plugin" message when I try to play any of my .ogg files.  Other players play them fine, I just like this one better. I tried the classic uninstall / re-install.  Can anybody point me to configuration or logging that will get this working again?

TIA

-Starboard!
