Answer 1

i probbaly didn't have to add ALL of that but that was the only help from google i could get that supposedably used virtual surround sound and didn't steal the sound... and ya i read the dmix was supposed to load by default but i guess it wasn't. hopfully i'll get to learn how to configure alsa on my own so i don't have to copy/paste/system specific edit... btw here is my old .asoundrc that wouldn't let more then one divice use it(first on i found that supposedly enabled virtual surround sound)
pcm.!default {
type hw
card 0
ctl.!default {
type hw
card 0
pcm.!surround51 {
type vdownmix
slave.pcm "hw:1,0"
pcm.!surround40 {
type vdownmix
slave.pcm "hw:1,0"
