Updated: NTS: Ubuntu, pulseaudio, alsa & surround

I got fed up with Ubuntu's default audio engine Pulseaudio - I don't find it normal that ~30% of CPUs power goes to processing simple backgroundmusic.

So, a solution:

apt-get remove pulseaudio // it removes also ubuntu-desktop, but i'll have to deal with this later, no immediate sideffects, probably affects only distro upgrades, can install it back anytime

asoundconf list // pick your soundcard

asoundconf set-default-card

and you should be pretty much done.

In my case (i have SB audigy LS card and 5+1 speakers), following was also needed, to make surround sound play by default:

--- add this to your ~/.asoundrc -----
pcm.!default {
type plug
slave {
pcm "surround51" # if u have 7+1, replace with surround71
channels 6 # if u have 7+1, channels 8 (?)
}
route_policy duplicate
}


# this is for mplayer to play surround by default
pcm.ch51dup {
type plug
slave.pcm "default"
channels 6
}
----- cut here ------


update 05.03: check this link for much more thorough guide as well.
I still have problem that i have no sound in flash, yet to resolve that..
