Logitech Z506 sound in front right speaker only

[sadbillsfan]

I have a logitech Z506 pc speaker system, but after connecting it I only get audio from the front right speaker - the other four play only static.

It's a 5.1 channel system plugged in to the onboard audio ASUS Sabertooth Z97 mkII motherboard.


Things I have tried:
Updating realtek HD audio drivers - no effect

Different speakers (connected an older logitech system, same issue) - this has led me to conclude that it's a settings problem somewhere.

Playing around with the audio balance levels. I can mute the other speakers (so that the static does not induce insanity), but cannot get them to produce sound.

A similar issue was reported here:
http/www.tomshardware.com/answers/id-2659586/logitech-z506-front-speaker-playing-sound.html

But in that thread the speakers were a few years old; mine are new.

Any help would be appreciated.

I tried fiddling with the slots - no luck. Is there a setting that I may be missing somewhere?
