OK, got off my ass "so to speak" and searched the web, answer chez le forum Ubuntu.http://ubuntuforums.org/showthread.php?t=314719
typed "asoundconf list" in terminal to show all the available sound devices ("Tra" and "the rest"). Then typed "asoundconf set-default-card Tra" and reopened player. Works great!.
All typing done in user terminal.
And the icing on the cake, while streaming music via the Logitech device, I can also make and receive Skype calls, with no compromise on sound of any device.
Congratulations Mint team.
