I have a MSI 915P motherboard with on board sound. Azalia link controller integrated in intel ICH6/ICH6R chipset, 8-channel audio codec CMedia CMI9880L. That lot means very little to me. It has a SPDIF output for Optical and co-axial which i feed to my AV amp..... but...... My question is this: In order to do away with my AV amp/processor/huge silver lump under the TV, is it possible to do all the decoding inside the PC (is it already doing the decoding in fact, or capable of doing it?) and output directly to a 5:1 speaker system via the jack outs (of which there is provision for 6 channels)? This is primarily because with the imminent migration of the HTPC from the floor to directly under the TV, I'll end up with two huge silver lumps of kit and I just want one. I would happily purchase an additional sound card to do the processing and the speaker system I currently have has a set of amps in the subwoofer to supply satellite speakers. It seems logical and would stop my girlfriend from passing comments about 'clutter' 'too many boxes' and 'just how many clickers do you need?'. Well being a bloke, the 6 'clickers' I currently have is the price you pay eh lads? Cheers, Jon.
