    Hi friends!

    Well I changed my /etc/modprobe.d/sound from this:

    alias snd-card-0 snd-intel8x0
    options snd-intel8x0 index=0

    for this:

    alias snd-card-0 snd-intel8x0
    options snd-intel8x0 index=0 id=i810 buggy_irq=1

    And, I booted my computer in single mode and I removed every snd kernel
    module and intel8x0 module according Richard's reply.

    Well, unfortunnely, my problem is not solved. But I found something
    strange now. After those changes, in the text mode my sound carding is
    working fine. But when I log in Gnome, open a terminal and play same mp3
    file using mpg123 the noise come back again. :-(

    Any suggestion for me?

    Regards,

    Jansen
