Pardon the endless questions...

Aren't most games encoded with EAX audio, rather than Dolby Digital and/or DTS? If that's the case, how with a HTPC would you get that EAX gaming audio decoded? If I simply pass the digital signal through the mb out to my reciever, the receiver doesn't know what EAX is. If I use a sound card, again, if I use the digital output the receiver isn't going to know what the EAX signal is, so I'd need to then use the multi-channel outputs from the card and purchse mini-plug to RCA cables and run all those cables out of the card and into the receiver's multi-channel analog inputs, no? If I did that, all Dolby Digital, DTS and EAX decoding would happen on the card and the receiver would simply receive the individual analog channel signals. Correct? (Much like you have to do with SACD and DVD-A)

Sounds like a pain in the tushy.
