    Hello.
    I recently upgraded my PC with a gigabyte GA-7VA-C
    motherboard and an AMD Athlon XP 2200. The motherboard has
    an on board sound card (Avance AC'97 from Realtek-ALC650).
    Everything seems to run well apart from the sound (no
    sound). In device manager there was a black exclamation
    mark (in a yellow circle) at the sound device. The message
    I receive when I click properties is a Code 10: This
    device is either not present, not working properly or
    does not have all the drivers installed. I tried
    almost everything. Remove the device, unistall the
    drivers, re-install them (either by using the CD that came
    with the motherboard or by leting windows find the
    appropriate drivers or by downloading drivers from the
    net) but nothing seems to work. The device does not appear
    to have any conflicts but I also tried to change the slot
    of another device that was using the same IRQ. However,
    windows assigned again the same IRQ so nothing changed.
    I have also tried to remove some devices and although the IRQ assigned to the sound card changed, there was still no sound.

    I finally downloaded the updated drivers from realtek's site. After I install them and reboot, the computer freezes. When I press ctrl-alt-del I can see that the program that is running is cmdninst.exe. Apparently there is something wrong there and windows cannot process this operation. I need also to mention that I disabled from BIOS, the games port because if this is enabled the computer will again freeze exactly in the same way I mentioned before.

    After rebooting and starting in safe mode and removing all the devices, the games port was finally installed BUT the problem with the sound remains exactly as before.

    Any help would be greatly appreciated.

    Is DMA enableld for all your IDE devices? This may sound unrelated but it's a problem i've had 2 or 3 times before with the AC97 Standard.

    DMA is enabled for the CD and the generic IDE disk.
    At System Devices in Direct Memory Access Controler there are two things: Reserved Memory with the option Reserve DMA Buffer which is unchecked and Address restictions with the option Restrict DMA transfers to Memory Below which is also unchecked.

    No other devices have the DMA option.

    At the Hard Disk Controllers in VIA Bus Master PCI IDE Controller there is a heading Dual IDE Channel Settings which is set to Default (Other options include Both IDE Channels enabled, Primary IDE Channel enabled, Secondary IDE Channel enabled and None). I do not know about this but I am just mentioning it if you think is relevant.
