Knowing the cause of the error is very important, as the solution will be influenced heavily by such information.

How to Fix It

When it comes to fixing error C00D1199, the first thing you will need to do is establish why the error is occurring. Once you’ve done that, the solution will become clear. Below, are a number of solutions that many individuals in your situation have used to combat this common issue!

Check Output Device

The error C00D1199 is often the result of Windows Media Player attempting to play audio out of the wrong audio device, the result of having the incorrect or several different audio devices selected for the Media Player. Anyway, to fix this problem, simply do the following:

1. First, boot into your computer with administrative rights.

2. Then swipe in from the right hand corner of the screen and click on Search. [Windows Vista/7: Start -> Type Windows Media Player (into the Search programs and files box) and click on Windows Media Player].

Swipe -> Search

3. The Search function should appear, type Windows Media Player into the Search Box and click on Windows Media Player in the results.

Search -> Windows Media Player

4. When Windows Media Player loads up, right click on the top bar and select Tools -> Options.

Tools -> Options

5. This will load up the Options applet, from here, click on the Devices Tab, and then double click on the Speakers Icon.

Device Tab -> Speakers

6. The Speakers Properties applet will appear, under select the audio device make sure the correct Sound Card or Sound Controller is selected, using the drop down list, then click on OK.

Speakers -> Audio Device -> OK

Download New Codecs

One of the most common causes for the c00d1199 error is due to the computer not having the required codec(s) to play the file. Codecs are basically small programs which allow your system to read different media formats.

Sometimes, when you attempt to run a particular file, it will ask for a specific plug-in to run that particular file, this is because the system lacks the appropriate codec.

The good thing is that codecs are free, with the All in One Codec Pack being the most comprehensive. So I recommend you give that one a download, from here:

Save File to Computer

It’s not uncommon for a user to attempt to load a file through the internet, which has inadvertently become corrupted. Situations like this, can lead to the c00d1199 error as a result of the players inability to play the content. The best way of getting around this problem is to download the audio or video file to your computer and play it from there.

Pressing the right button on your mouse and selecting save as; you can download the file(s) to your system.

Check File Type

It’s very important that you have some understanding of the type of file(s) you’re trying to open. It’s not uncommon for users to attempt to open a file that is part of a series. If a file is part of a series, then you will need to download all of the corresponding files, in order to play the audio or video file. So keep that in mind.

Run Registry Scan

The Windows registry is essentially the database, a place where all the most important data is stored, such as Windows settings, configurations and options. The registry is the most important part of Windows, and is what most applications will refer to when attempting to carry out specific functions.

Unfortunately, because of the registries importance’s, it makes it highly susceptible to corruption, which is a catalyst for a plethora or different problems for your system.

It’s often the case that the Windows Media Player will attempt to read various files from the registry, and find that they are corrupted, thus prohibiting the player from carrying out its primary function.

As a solution, it’s recommended that you regularly scan your registry for errors and file corruption, using a registry cleaner tool like SpeedyPC Pro, which is a multifaceted application, with the ability to not only repair various computer errors, but also optimise system performance. Anyway, you can acquire this powerful tool from here:

Check Sound Card Settings

Another method that you can use to resolve the C00D1199 error involves checking your sound card settings. You want to ensure that everything is configured correctly, as an improper configuration can lead to all kinds of problems.

Update Drivers

If your sound card settings are configured as they should be, but the error still persists, then it’s advisable that you look into updating your device drivers. Now, there is a good chance that the error could be due to one or more incompatible drivers on your system, which is why I recommend updating as many of them as possible.

When it comes to updating your device drivers, you have two options, the first is to manually visit the website of all the devices attached to your computer and locate, download and install the latest devices you find there.

The second is to use an automated driver updater tool like DriverAssist, which will automatically search the internet and find all the latest drivers for all the devices attached to your computer, and install them. Personally, I recommend DriverAssist, and that’s because of its ease of use, efficiency and speed, as the manual option can be very time consuming and complicated, depending on your level of expertise. Anyway, you can download this powerful tool from here:

Run Malware Scan

It’s also possible for you to experience errors with the Windows Media Player when one or more of the program files are corrupted due to a virus infection. In order to fix and prevent such errors, it’s important that you regularly scan your system using your antimalware tool.

If you do not have a security suite on your computer, then I recommend you check out my post on the best antimalware tools.

Use an Alternative Player

The file you attempted to load may simply be an unsupported format on Windows Media Player. That leaves you with only one option, to use an alternative media player. There are many of them around, but I personally recommend VLC Player, and that’s because of its wide support for a number of different audio and video formats.
