Windows Media Player doesn't play songs "Windows Media Player encountered a problem while playing the file- c00d11b1"

Hi Community! Windows Media Player on my desktop decided to stop playing some of my music. It's the strangest thing and I haven't found a solution online.

First, when I try to play a file it seemingly arbitrarily decided to dismiss, the player gives me "Windows Media Player encountered a problem while playing the file." and simply doesn't play it. Clicking on web help brings me here: http://windows.microsoft.com/en-us/windows7/c00d11b1. Since the problem arose, if Media Player rejected it, it hasn't played and if it accepted it, it did play. Not a random case of, one minute it plays, the next it doesn't. Something about the files is determined and set.

Second, these are files that have played before flawlessly through Media Player. All except the single track I downloaded through Amazon, which is how I discovered the problem to begin with. As far as I'm aware, the files it refuses are all .mp3s. The .wmas I tested all seem to play. So do roughly half of my .mp3s. Various video files all still work too.

Third, as far as I am aware, none of my music has DRM. I can copy any of it to a flash drive and play it on my car. It plays on other devices and programs like RealPlayer or VLC. I believe the files are not corrupt.

Fourth, and this one's possibly not related but... I recently installed a Blu-ray drive on my computer and tried to install codecs to play Blu-rays. I have since learned that I will need to make another monetary investment for a program that can play them due to copyright issues or whatnot. I'm holding off on that for now. That aside, the library of codecs I had should still be in tact, but I noticed Media Player's failure shortly after that debacle. Mentioning it in case it offers a clue.

I have run Windows Update

I have tried un/reinstalling Media Player

I have tried reinstalling codecs

I'm running Windows 7 Ultimate in 64-bit and My version of Media Player is 12.

Let me know if there's more information I can give you.

    The problem still isn't fixed, but I found some potentially useful information. As per some other advice I found on the wild web, I tried to let the control panel fix the issue:

    I went to Control Panel > Find and fix problems > Programs > Windows Media Player Settings.

    From there I ran the troubleshooter and it determined my configuration settings might be set incorrectly. If I view detailed information, it claims the detected problem was fixed, but if I run the troubleshooter again, it gives the same results. Testing the troublesome files still proves fruitless.

    Does this give you any hints? I'd still really like this fixed.

    Yes, you can create a registry key named "DisableProtectedAudioDG" and then change the value/assign a value "0" to the key. 

    Can you confirm if I've done this correctly? There seem to be numerous ways to write a key and I've never done it before. What I have done here does not fix the problem. I will be trying the system restore solution soon.

    Thanks!

    EDIT: It appears the only two system restore points I have are from the 16th and 18th this month. Too late. I suspected that it wouldn't solve the issue anyway after reading other users troubleshooting this problem. It's too bad I can't try it though. This registry issue seems to be my strongest lead.

    Hi Beneli,

    Thank you for keeping us posted.

    Yes, you can create a registry key named "DisableProtectedAudioDG" and then change the value/assign a value "0" to the key.

    If this doesn't help and the file were playable using Windows Media Center, let's restore the computer to a point prior to this issue:

    Note: Once again, please make sure that you have the registry files backed up as explained earlier before making these changes.

    Let us know how it goes. We will be glad to assist you further.

    Hi Beneli,

    Welcome to Microsoft Community.

    The error code that you receive when Windows Media Player doesn't play the files is c00d11b1.

    This error code might occur if the sound card's driver is corrupt or is not running normally.

    Please refer to the manufacturer's website to download and install the latest sound card's driver for the computer. You may also check if the sound device are configured properly.

    Refer to these links and check if it helps:

    Important: This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the windows help article below.

    If the issue still persists and as you were able to play the files earlier on the player, restore the computer to an earlier point and check if it helps:

    Please let us know the results.

    Thanks for the reply, Pinaki!

    I have now tried uninstalling and reinstalling my sound card drivers. No luck (but at least, no additional problems either).

    I also tried the regedit solution in your second link and I found something curious. When I navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Audio I don't have any options for DisableProtectedAudioDG. Obviously I can't change the value from 1 to 0. Do I need to rewrite the key, or is there a way to replace it?
