No sound from my PC

  1. hi...i wonder if anyone can help me i have no sound coming from my pc. i have checked every possible thing ie.device manager all is good there.volume etc no mutes checked all the cables alls good even plugged an mp3 in to check the output through the speakers all clear...but still no sound from my pc...i downloaded all the latetest drivers everything is up to date.

    i was on the onboard sound system REALTEK which was ok...even after i had installed a HD3450 ATI RADEON GRAPHICS when i check in device manager ATI SOUND DRIVER comes up but no sign of REALTEK?

    i checked the programme files and opened the REALTEK folder and tried to run the sound mixer? i removed the folder and downloaded a whole new REALTEK which is installed...still no go...

    if anyone could help me in any way at all i would be really grateful as i am now puzzled what to do now apart from disabling the ATI sound stuff and installing a new soundcard etc...which i dont really want to do because of the cost...

    HEEEEEEEEEEEEEEELP...regards roy

    I am some what confused. You installed an ATI HD 3450 graphics card and now your audio drivers have disappeared?

    hm ... does your card have an HDMI output, by chance?

    Are you sure that your graphics driver is compatible with your MB? ..

    yes indeed i have just checked and the graphics card does have an HDMI output? do you reckon that this could have knocked out the onboard sound and if so would it be possible for me to disable the ATI sound driver in device manager and then enable the onboard sound in bios?...i dont know if the graphics card is compatible with my motherboard which is a MSI.ms7173...should have checked before i bought it i guess but it was cheap so beggars cant be choosers!...hahahahahaha...

    As for the ati2dvag driver error, you might try updating your BIOS from the link techsuitor posted.

    Hi roy

    Pygmus hit it on the head in his earlier post when he asked about HDMI: you installed an ATI graphics card with HDMI so it comes with its own sound hardware.

    > There's no reason you can't have BOTH ATI and Realtek enabled (i do something similar on machine even as we speak :) )
    > Part of the "trick" is making sure
    ===> Both the ATI and Realtek sound hardware is detected
    ===> Both ATI and Realtek drivers are installed and the devices enabled
    ====> Make sure the right default playback device is enabled!!! (Look at footnote #4 at end of Reference Guide to Help Setup and Troubleshoot Windows Audio and Sound Cards
