    Please see the post I just posted a few minutes ago
    trying to help Trace Green with a problem with the same
    driver.

    My suggestions are you've either not unmuted the sound
    settings or you've got the dreaded "AC97 Quirk" and
    need to be focusing on Headphone volume to control
    actual master volume.

    If you have Linux kernel source installed, check out
    <linux kernel source dir>/Documenation/sound/ALSA
    Configuration.txt for info on the "quirk".

    If you haven't got amixer on your machine, apt-get
    alsa-utils to get it then use amixer to check and if
    necessary modify the mute state and volume of your
    Master, PCM, and other settings. If this succeeds and
    doesn't help try modifying your Headphone settings
    (unmute and set vol) as you may have the "quirk". If
    you do you have the option of trying to get the driver
    to work around it or just living with it (which is what
    I'm doing so far).

    For the rest of the detail, see the post I just posted
    before this.

    PS your lspci and lsmod output look healthy, at least to
    my no-better-than-mediocrely-tutored eye. But if you
    haven't set volume and mute settings on your mixer
    since switching to the ALSA driver, they'll be muted,
    dollars to doughnuts...
