All of my six (so far) systems using FC11 were clean installs, four from LiveCD, 
one from DVD, one from DVD image NFS mounted. Oh, and a test install from USB 
made from the snapshot DVD, on one of those machines later reinstalled.

Four of six had simple output to the laptop speakers work after install, the two 
  desktops had two channel from the sound card, no setting I've found will 
enable the other speakers from any source, even on hardware which had 5.1 with 
Windows and FC6.

Your point about upgrade is well taken, three of the six worked worse after 
upgrade from the install media to "current" using either yum (cli) or the update 
menu item. Go figure.
