Hey thanks for the reply.
Selecting the virtual surround does not give me 5.1 surround, its like a mixer button which copies front speakers (I think).
So I bought the S/PDIF cable and I cannot connect it to the motherboard (GIGABYTE H87-HD3) which has both S/PDIF Out and S/PDIF In (inside) options.
I have just a few questions:
1) Like you said, if I use a converter for optical, will going analogue give the same sound quality? because I heard optical is way better than analogue. (according to my knowledge.)
2)What is the exact thing needed here to connect my S/PDIF In. (Motherboard has 3 S/PDIF In pins inside)
3) Would it give me 5.1 DTS or AC3 for movies only for sure? Or am I wasting my money?
