    Windows XP Home Edition
    IE 7
    Windows Media Player 11
    (All of these installed a week ago)

    Webpages with mp3 backgrounds (i.e., bgsound) are not played by IE7; there is no sound.

    What works:
    - Playing the same file directly from my PC (no IE).
    - Get sound OK from this webpage using another PC.
    - Get sound OK playing YouTube vids

    - Browser Setting - Playing sound from webpages is enabled.
    - Volume: All volumes up; no volumes muted.

    - A popular registry import fix (no change); re-imported original key settings
    - Installed Windows Media Player SDK (no change).
    - Ran FileMon during the time when the webpage would be initiating the mp3. Some files were shown as "not found", but those may normally not be found, for all I know.

    Add-Ons listed by IE:
    Adobe PDF Link Helper
    Diagnose Connection Problems...
    HP Clipbook
    HP Print Clips
    HP Print Enhancer
    HP Smart Select
    NitroPDFBHO Class
    PDF Download
    PDF Download - Options
    Shockwave Flash Object
    Windows Messenger

    I don't see a Windows Media Player ActiveX listed. Should there be?

    Yes it should.

    Open your Internet Explorer Options, under Security tab, and check your ActiveX settings.

    Have a look at this sound troubleshooter to se if anything could apply to you:

    If you have them, uninstall and then re-install your audio drivers. Sometimes this will fix a glitch.

    Check that the Windows Audio service is set to Automatic and Started (Start => Run and type in "services.msc" {without the quotes}).

    If it's missing, download and run this fix:
    Line 371 - Left

    Open Device Manager (Start => Run and type in "devmgmt.msc" {without the quotes}).
    Expand System devices, and check that 'Plug and Play Software Device Enumerator' is present and is "working properly".
    During the routine you may see "Driver is enabled but has not been started".
    If it's not present, or not "working properly", or you get the above message, see at the end of this post.
    If it's a case of no audio just on certain websites (flash video). Read the following:
    If it's a case of just no system sounds (CD's play OK) - the beeps and clicks you hear when performing actions in Windows, download and run the fix here:
    If you have DirectX installed, go to Start => Run and type in "dxdiag" {without the quotes}
    Run the Sound tests.
    If you don't have it, you can download DirectX.
    If it's a case of no audio at all, and you've ruled out any audio driver problem, then run these routines:
    (You may want to print this off.)

    First the hardware ... check that your card is being recognized by your computer.
    Right-click on My Computer and select the Hardware tab.
    Click on the Device Manager button and scroll down to Sound, video and game controllers.
    Click the + sign to expand this section and make sure that your sound card is showing and that there are no yellow ! exclamation marks and no red X's against any of the devices listed.

    If all is OK, proceed to check your software settings:

    If you have a music file that's fairly long (10 minutes) or you can set to Repeat, open it and start it playing so you will know if you hit on a solution.

    Go to Start => Control Panel => Sounds and Audio Devices.

    In everything below, be sure to click the OK button after every window.

    First, under the Volume tab
    Check that the Device Volume slider is at least one-third way across.
    Check that the Mute box is cleared (unchecked).
    Check that the box Place volume icon in the Taskbar is checked.
    Click the Advanced button.
    Check that there are no Mutes and that the levels are at least one-third way up in all sections.
    Click the Speaker Volume button and check that the levels are set somewhere in the middle.
    Click the Advanced button.
    Check that Speaker setup has Desktop speakers selected.
    Click the Performance tab and check that both sliders are set to the far right.

    Next, click the Audio tab
    In the Sound Playback section check the selected Default Device. It should be set to your sound card and not your modem or anything else.
    Click the Volume button.
    Check that there are no Mutes and good levels (none at zero) for at least Volume, Wave, CD Player, etc.
    Click the Advanced button. This is the same as you saw in the Volume tab, but re-check it anyway.
    In the choice of speakers, Desktop speakers should be selected.
    Click the Performance button.
    Check that both the indicators you see are set to the far right.

    Next, click the Hardware tab
    In the list you see, highlight (select) your audio device from among the listed hardware (drives and other stuff).
    Click the Properties button.
    Check to see if it says "This device is working properly". If it doesn't we're looking at a driver problem.
    Click the Properties tab (not the Properties button).
    Expand the Audio Devices item (click the + sign) and select (highlight) your audio device.
    Click the Properties button.
    Check that the round "radio button" for 'Use audio features on this device' is checked.
    Beside Status: it should say "Driver is enabled and working properly".
    If no joy so far, back in the Hardware tab, click the Troubleshoot button.
    You can run a series of tests from here.
    'Plug and Play Software Device Enumerator' is missing or not "working properly".

    This fix may work, although this should normally be taken care of by reinstalling the audio drivers:

    1. Insert your Windows XP CD and find swenum.sys - either in DRIVER.CAB or SP2.CAB. Copy it to the proper location noted above. Also put it in C:\Windows\System32\drivers. If you don't find it or can't do it, just skip to step 4.
    2. Do a search in your Windows folder for machine.inf. There may be more than one location, but note down which one you select.
    Open it (double-click) and locate (near the top) the line "ExcludeFromSelect=*". Put a semi-colon followed by a space at the beginning of this line to disable it.
    3. Look for this line near the top: "SWENUM.CoInstallers.CopyFiles = 11 ; %windir%\System32".
    "%windir%\System32" indicates that the file swenum.sys should (normally) be located in the C:\Windows\System32 folder.
    Close machine.inf, saving changes.

    4. Go to Control Panel => Add New Hardware. Follow the wizard and manually select to Add System Device. Click on 'Have disk'. Navigate to machine.inf. You will have to do a search in your Windows folder. In the list of Standard Devices on the left, select "Plug and Play Software Enumerator" on the right. Finish the installation.
    Restart the computer.

    OK, I have a better grasp of the problem...

    There is something about the online mp3 files themselves which IE does not like. It is not a file corruption. The files are rather 'low grade', e.g. 22050 Hz, 16 bit, etc. These files will not play on my new IE/WMP install. IE will not play offline copies of these files either.

    However, if I replace a file with a 'better quality' version---e.g, 44100 Hz, 32 bit---IE plays them just fine.

    Does this mean I have to improve/correct my codecs?
