Now that the Surround Sound is properly working, I took some time setting the speakers to really give me enveloping sound.
By default on pretty much everything I've watched/played, the speakers were FAR too "forward" for me, with the sound coming from the screen. The music often over powered the voice, and surround sound was pretty anemic.
Eventually I maxed out the subwoofer (Jenn like Big Boom), maxed out the rear speakers, set the center speaker, which carries most of the dialogue to default, and the left and right to negative 5 volume.
That gave me a nice surround sound finally, with the V'Ger "Wok" scenes REALLY feeling like I'm in the wok with them, with proper echoing and good rumbles instead of the sound coming almost completely from the front. The sound is still a little tinny from the regular speakers, but it's probably cause the speakers are kind of cheap.
Now if you'll excuse me, I need to go beat up on Ganon in Breath of the Wild in Surround Sound. :D
