BurrMan, when opening said speaker sound thingy,
under "playback tab" there is just two-- "speakers-realtek high def audio default device" with GREEN check mark and " speakers- 3 Logitech USB Headset" in the playback box.
In "Recording" tab-- 3 are available----"microphone" and "line in" both NOT PLUGGED IN
"Micophone Logitech USB headset" has GREEN checkmark
In "Sounds" tab standard factory looking I think
In "communications" tab- reduce the volume of other sounds by 80% checked
Clues ??, rj
