    Ubuntu Karmic ALSA problem

    Hi all,
    I have a 5.1 surround system but sound only plays from two channels. I was able to identify the source of my problem : when I set "Mic Jack" and "Line Jack" in alsamixer to "Line out" all my speakers seem to work, but the problem is that after a couple of seconds the Mic Jack setting reverts to Mic In for no apparent reason. Is there a way to force ALSA to "remember" the config wothout changing it?
    Please note that I'm also using the "Analog stereo output" profile in sound preferences since it's the only one that gave me some kind of result.
    Thanks in advance

    I also noticed that the channel mapping is wrong : my rear right channel is marked as LFE ( it says rear center) and my subwoofer gives some kind of distorted sound , in terminal it says "Rear Right" , this might explain the lower quality sound in comparaison to windows.
    Does anyone know how to fix this too ?

    EDIT: My problem was actually unrelated.
