    First look in your BIOS. Is there an entry for Onboard Audio? Is it set to Enabled?

    Also, i'm going to guess the UNKNOWN device you see in DevMgr appears under USB category? (in which case, it's not at all related to your onboard sound card)

    and it got installed.

    1) Memory
    I'm not sure what you're asking about memory but, in any case, you should post a separate thread clearly stating your question and computer system specs so others more familiar with memory issues might answer

    2) Re: Your sound problem
    > Your dxdiag report confirms what you observed: Once you enable Onboard Audio the MS UAA Bus Driver and your sound card are detected and drivers installed
    > Based on the report, it seem Windows is happy with the sound card and drivers and it looks like everthing should be OK (see snip below)

    So have to next wonder about the audio plug/jack and speaker connection. Are you plugging your speakers into the rear output jack?? (Note the device description is Realtek HD Audio rear output)
    > Have you tested the speakers on another computer? you know they work?

    I would also first test if you hear Windows sounds (before you start testing for any other missing sounds) Click and see footnote #3 in this Guide

    I wonder if the audio port itself might have failed.

    You could try booting into Knoppix (see this post but just look at step #2 about how to create a Knoppix Live CD). Boot into Knoppix and try using the Knoppix media player. If sound still fails under knoppix you'll know its not a Windows specific problem but related to your hardware (probably the audio connector - since Windows installed the drivers for the sound card OK)
