GF104/106/108 GPUs also have a built-in HD audio processor with 8 channel LPCM output but also has the ability to bitstream Dolby TrueHD and DTS-HD MA straight to the receiver without decoding it first, instead letting the receiver do the decoding.
The onboard audio on your motherboard is totally unused, it is not processing anything because the HD audio processor in the GPU does it. Please don't spread misinformation, gerardfraser.
Well I am going to turn off me onboard sound and try this.
Spread misinformatiom LOL
