5.1 Audio Help

Hello, a novice regarding this topic but I was wondering if anybody could confirm whether or not this home cinema system: http://www.bestbuy.co.uk/product/1000157007/yamaha-yht294-51-av-receiver-and-speaker-system.aspx?ref=AW&loc=HotUKDeals&awc=2533_1311790229_8cd94a52626b4163bec82df7875e1f44 (Yamaha YHT294 5.1 AV Receiver and Speaker System) will enable me to play 5.1 audio from a WDTV Live?

If so what connections would I need, I have a spare optical port on the WDTV Live and my HDMI one goes into the TV.

Help appreciated!

Post a link to the devices manual on the manfacturers web site.

If that link doesnt take you direct to the manual its listed under support.

Thanks!
