HTPC Optical/Coaxial Audio out to Receiver = Done Deal?

Working on putting together a HTPC. So long as my motherboard as a digital audio out (either optical or coaxial) and my receiver supports those connections, am I good to go for digital audio? My receiver ca decode the signals, I just need to be sure that the MB will be outputting the right stuff.
 
Yeah, but SPDIF isn't the best digital audio these days.

You probably won't notice unless you're playing Blu-Ray though.
 
No games for now. Maybe some MAME stuff in the future, but I'll setup a standard analog connection for that.

My receiver is a few years old now (6ish I think) so optcial audio is the best I gots for now.
 
The only thing you will need to worry about is Windows modifying the bitstream. You will need to make sure that volume is set to 100% and ouput is set to 2 speakers. Depending on the drivers there might be a selection for SPDIF or Digital output that needs to be selected. If a DTS or AC3 stream is modified in any way all you will get is static. Once you tackle that you will need the proper software and/or codecs to do the SPDIF passthrough to your receiver. I personally use AC3 filter and select the SPDIF preset. If everything is working correctly when you play a mulit-channel movie your receiver should automatically switch to DTS or Dolby Digital and you will have surround sound.
