Wii U and Sound Issue

[Reemul]

(Cross post from elsewhere)

Hi all, purchased a wii u today.

my PC is in the front room, I have a 23" monitor. With dvi, VGA and hdmi connections but no speakers.
I have a set of Logitech z54000 5.1 speakers with centre console with optical and co axial connections that support 5.1 and dts. I plug in my ps3 and xbox360 via optical to get sound.

Now apparently the wii u doesn't support 5.1 so I'm unsure how to get sound out of the speakers/console.

i won't use the consoles on the tv as my wife watches tv on it so at a loss at the moment as to what to do.

I could buy a 27" monitor with speakers as well as an option but no doubt the wife would kill me after buying a Wii U as well

Any ideas?

Edit, just found a headphone socket on the side of the monitor, maybe i could use this and headphones for sound.
