Decoder problem in W2003 SP2

Discussion in 'Windows Media Player' started by Pavel Ivashkov, May 3, 2007.

  1. It seems for me that in W2003 SP2 WMV decoder has been updated and cannot
    play some WMV files. I have two samples of such:

    (6.3 MB)
    (link from

    (43 MB)
    (link from

    The video plays fine but the sound is crappy.

    A similar issue I found here: -- don't know if it any
    related, just FYI.

    Can someone confirm the issue with W2003 SP2 on files listed above? Is it a
    known issue? If not, how can I submit this issue to responsible MS team?

  2. Neil, those are not .exe but .wmv files, please navigate to first link and see.

    So, I'm opening the file from the second link and looking into Properties...
    Audio codec: Windows Media Audio 9 Voice 20 kbps, 22 kHz, mono
    Video codec: Windows Media Video 9

    (man, I hate editor window on this site, why it moves my cursor to the top
    of the message whenever I switch between windows??)

    Video decoder is fine, but audio is not. It tries to decode and I can hear
    and distinguish words but it's full of metallic noise. The experience is very
    similar to what guys describe inhere

    What do you mean by "actual system"? It is Windows Server Std 2003 + SP2.

  3. Oooch, sorry, that was my mistake as for the linked files. You are right,
    they are .exe - just self-extracted .wvm's. I rarely use self-extraction
    feature and instead unpack them directly in my file manager, that's why I
    believed they were .wvm. Sorry for that.

    To give you a background, I am a developer and Windows Server suits my work
    style very well. It's only lately that I became interested in different
    webcasts and video shoots on IT. So, I have this issue and another with
    livemeeting here
    which relates to audio codec too. Other than that I'm pretty happy with
    server platform for my desktop :)

    Back to this issue.
    I'm on 32 bits, so it doesn't apply.
    This one is for XP and WMP 11, refused to install.

    So, I'm on Windows Server Std 2003 (32 bit) + SP2, WMP10, audio integrated
    into ASUS P5GD1-VM (i915G, Realtek ALC861). And now I can confirm the same
    issue on another (though somewhat similar) hardware: ASUS P5GZ-MX (i945GZ,
    Realtek ALC883), W2003 (32 bit) + SP2.

  4. Audio codec: Windows Media Audio 9 Voice 20 kbps, 22 kHz, mono
    Just tried to check this - there goes the difference. I used Windows Media
    Encoder, and it provides me with three encoders for audio (CBR):
    * Windows Media Audio 9.1
    * Windows Media Audio 9 Voice
    * Windows Media Audio 9.1 Professional

    Only for "Windows Media Audio 9 Voice" I here the cracking sound, other two
    are fine (no matter what bitrate I set).

    Going to update Realtek drivers, thanks for the link..

  5. No, updated drivers did not help. I checked audio settings, speaker setup (I
    use headphones) and used different players - all the same. So, it's WMA 9
    Voice decoder to blame.

    What I'm going to try next is to get wmadmod.dll from W2003SP1 or some KB
    and replace it in safe mode..
