    Hi friends,

    I bought a Compaq Presario V2000 laptop and I installed Debian sarge on
    it. For now, everything is working, except the sound card. The driver I
    am using is intel8x0.

    Well, a read a lot of things on the Intenet about this driver and I did
    a lot of them but my problem is not solved: when I boot my computer and
    try to use my sound card I get a poor quality sound with noises.

    I blacklisted intel8x0m module in /etc/hotplug/blacklist according I
    read in a tons of maillist archives but this not solve my problem. To
    get a good quality sound I need to run alsaconf every time I reboot my
    computer. I have noticed a small difference in lsmod output between
    after a reboot and after run alsaconf.

    I am using Debian sarge with kernel 2.6.8-2-686.

    Can anyone provide me some help or hint to solve this?

    Follow I put some useful informations:
