5.1 channel PC sound card with digital coax?

[djlachlan123]

I'm looking for a sound card (PCI low profile or USB) that outputs via a digital coax connector so I can watch movies in 5.1 surround with my receiver? My motherboard only has 3.5mm aux connector that is only stereo.

Don't want something that is over $50 preferably.

I have Trust 512DX 5.1 you just have to find it with additional bracket or make DIY since it has datasheet for pins which are used for Digital, my friend used it and it has pretty much good optoins and didnt die in 1 year of usage (release date is from 2003).
