go to a command line and type:
that should start up a very basic looking equalizer within the command line.
press right to go over tone, and press "m" to turn it on/off. once it's on, adjust the bass/treble to how you like it and adjust anything else (you adjust how loud your rear speakers are from within here too)
exit it by pressing "escape" then do
Code:
su
(enter root password)
alsactl store
to store your equalizer settings
now you can exit the terminal and you should have your new equalizer settings working and saved
