    APM, ACPI and system sounds

    Although this is a new topic, it continues the questions/discussion concerning getting system sounds
    to work with the Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 01). The
    original topic can be found at:
    http://kubuntuforums.net/forums/inde...opic=3084096.0

    Advanced Power Management and Advanced Configuration and Power Interface
    and system sound problem

    Packages: apmd and acpid

    First, according to the description for apmd from Adept Manager:
    Debian kernels are built with APM support but it is disabled by default.
    You need to boot the kernel with the "apm=on" option if you want to enable
    the driver."

    I verified that this module was installed. I also had the acpi* modules
    installed. The only way to get functioning system sounds was to add "acpi=off"
    to the end of the kernel line in the /boot/grub/menu.list file (see the link above).

    I have uninstalled the apmd package and the following acpi* packages:

    acpi
    acpi-support
    acpid

    Additionally, I unchecked "Start during boot"
    (K Menu | System Settings | Advanced | System Settings | System Services) acpid and apmd.
    I then removed the "acpi=off" from the kernel line in /boot/grub/menu.list and rebooted
    the system. The result: No system sounds. Adding "acpi=off" back to the kernel line and
    rebooting results in functioning system sound.

    K Menu | System Settings | Advanced | System Settings | System Services lists both acpi and
    apmd, even though the modules were uninstalled. lsmod does not identify these modules. So why
    does adding kernel option "acpi=off" work to get system sounds working when the module it is
    turning off isn't even loaded!?

    I am convinced there is a conflict between a power management module(s) and the sound modules.

    How do I get a listing of the modules that are actually complied within the kernel, and not those that
    are actually being used once the system is booted?
