How to play downloaded 5.1 flac music files?

Hi

I would like to try setting up a hi res 5.1 surround music room and play downloaded 5.1 flac  music files from  ITrax.com who specialise in the recording of this type.

I can play these files on my laptop through foobar 2000 and windows media player but I havnt got a digital out on the laptop.

Does anyone one have any idea on what player could be used to send this music to my av amp in the connection path.
