Missing Codec in Media Player

Posted on 2004-11-05

I am trying to open a file in Media Player 10 and it tells me that it could not locate one of the Codecs to play the .wav file.  It is looking for dvi_adpcm (0x0011) Intel Corporation codec and I think I have it installed, but it still does not work.  Could anyone please help me get this .wav file to play in Media Player?  Thanks.  It is Voice Mail so it is very urgent.  Thanks.

    - Since you have WM Player 10 installed your OS must be XP.
    - Do the following to check which audio codecs are installed.
    - Click Start > Control Panel > Sounds, Speech & Audio Devices
    - Select Sound & Audio devices
    - Click the Hardware tab
    - Select 'Audio Codecs' in the list and click Properties
    - Select any codec in the list and click Properties again to see format it plays back.
    - If you need to download any specific codec, you can download most types from the following link...

    Good Luck!

    - Continuing my last post, just check if you have the imaadp32.acm in your list of audio codecs (It should be able to decompress the file which requires the Intel dvi adpcm codec).
    - If it is not in your audio codecs list, check if the file is present in your system32 folder (If the file is present but not in the audio codecs list then it only needs to be registered in your registry).
    Click Start > Run and type regedit
    - Go to HKey_Local_Machine > Software > Microsoft  > WIndowsNT > Drivers32
    - In the right hand side pane, Right Click and create a new String with the name msacm.imaadpcm
    - Right click the string and choose modify
    - Enter the name of the codec file 'imaadp32.acm' as the value.
    - Now the codec should appear in your list of audio codecs.

    Good Luck!

    ...adn, if iaadpcm.acm exists, maybe is not registered, then run regsvr32 imaadpcm32.acm in system32 folder.
