No surround sound with Creative SB Live! card

[David Demelier]

Hello,

I have an old SB Live! card with a 5.1 speaker set, but i can't get 
sound from center and rear speakers with mplayer.

I'm using the snd_emu10kx driver and when I try to play a DVD I get 
sound only through the front speakers (and LFE) like a 2.1

Adding -channels 6 to the mplayer args does not help.

Cheers,
