Can't hear any difference
I watched/listened to the video but couldn't tell any difference when it was on or off.
Admitedly, I wasn't listening with headphones, but via my AV receiver and speakers in analogue 2.0 mode.
My computer is connected via 6 channel analogue to the 6ch Ext. Input and also via digital optical S/PDIF. When the digital input is selected, my AV receiver can upmix 2.0 audio to 5.1 so thats what I have it set to most of the time.
