Sound out from A75M-HVS

I have just bought a new PC with an ASRock A75M-HVS motherboard which I haven't set up yet. On my previous PC, the MB had an optical out, which I hooked up to a Creative decoder amp and 5.1 speaker set. The new MB doesn't have an optical or coaxial output just 3 audio sockets labelled - 'HD Audio Jack: Line in / Front Speaker / Microphone'. It says in the specs that it supports 5.1 CH HD Audio (VIA® VT1705 Audio Codec) and THX TruStudio™.

What's the best way of hooking this up to the decoder amp? The only way I can figure is just via a standard 3.5mm jack lead from the front speaker socket. Surely this can't be correct??? Would I be better off just getting a cheap sound card with optical out?

Also, can anyone tell me what a 'VT1705 Audio Codec' is?

Ignore the codecs and such. You haven't specified which amp you are using, so I'm going to imagine an amp that supports two microphone ports and a headphone port. Anyways, here is what I recommend WITHOUT the amp:

If you can include your amp, I can draw a new diagram with the amp. For now, I would try out this setup. I would however, recommend a new sound card to make things 10 times more simpler; the Xonar DG is relatively cheap and provides better sound quality than what your motherboard current has to offer.

Thanks very much for your very detailed reply reprotected. I don't what the amp is, however, not half an hour ago I actually ordered a Xonar DS 7.1 after looking at the DG; but thanks again.
