Do you think that may be the reason the sound is choppey whilst playing DTS HD MA or DD TRUE HD whilst not using DXVA2 ? Thanksno, no...and here is why- if you're passing through audio via hdmi, it doesn't matter how many speakers you tell windows to passthrough. it'll only passthrough the audio codecs within the movie file. that is why it called "passthrough".
you need to set it to stereo because when you play a non passthrough audio format (usually 2ch stuff) stereo will stay as stereo and pass to the amp cleanly, and the other audio codecs (5.1/7.1) will be passed through with raw codecs.
