Twitch is a live video streaming platform owned by twitch interactive. The platform was introduced in June of 2011. The platform consists mostly of Video game streams, E-Sport Competition streams, Music Broadcasts and has a recent trend of “Real In Life” streams.

However, quite recently a lot of reports have been coming in of the users who are unable to watch the streams on the platform and an error message that reads “Media Resource not supported” pops up. In this article, we will inform you about some of the reasons due to which this error can be triggered and provide you with viable solutions in order to ensure complete eradication of the problem.

What Causes the Twitch Error 4000?

The cause of the error is not specific and it can be triggered due to a number of reasons, However, the most common ones are:

Now that you have a basic understanding of the nature of the problem we will be moving on towards the solutions.

Solution 1: Clearing Cache and Cookies

Cache and Cookies are stored by the browser in order to decrease the loading times. However, if they are corrupted they might cause problems with loading the site data or the streaming service of the site. Therefore, in this step, we are going to clear the cookies and the cache for the browser. For which:

1. Click on the “Menu” button on the top right side of the browser.

   

2. Select “Settings” from the dropdown.

   

3. Scroll down and click on “Advanced“.

   

4. At the end of the “Privacy & Security” heading, click on the “Clear Browsing Data” option.

   

5. In the time range, select “All time“.
6. Make sure that both the “Cookies and other site data” and “Caches image and files” options are checked.

   

7. Now click on the “Clear data” option.

   

8. This will now clear all the cookies and the cache, open the site and check to see if the problem persists.

Solution 2: Refreshing the Site

In some cases, the computer might have been disconnected from the internet while you were trying to open the site and this might have interfered with the loading process of the stream or the website. Therefore, in this step, we are going to be refreshing the page in order to make sure that the stream is loaded properly. For that:

1. Open the tab in which you tried to load the site.
2. Click on the “Refresh” button on the top left of the window by the address bar.

   

3. Wait for the stream to load and check to see if the issue persists.

Solution 3: Closing Other Applications.

If there is any other application opened up on your computer that provides audio feedback, it can cause issues with the twitch stream as it can interfere with the playback service of the site or the browser. Therefore, it is recommended that you close all other applications, restart the browser and close any other tabs on the browser as well.

Solution 4: Selecting Default Audio Drivers.

It is possible that the correct audio drivers for the output device that you are using might not be selected. While the output device might work correctly in some applications it might not work for the others. Therefore, it is recommended that you chose the correct audio drivers from the Windows Settings. For that:

1. Right–click on the sound icon in the bottom right corner.
2. Select the “Sounds” option.

   

3. Click on the “Playback” heading.

   

4. Identify the correct audio drivers for your output device and “Right–Click” on them.
5. Select the “Set–Default” option to select them as the Default Drivers.

   

Solution 5: Changing Autoplay Options.

If you are using the Chrome browser, the autoplay feature of the browser might be interfering with certain elements of the game and thus causing the error. The autoplay feature has a bug where it sometimes might trigger this error. Therefore, in this step, we are going to be disabling the autoplay feature. For that:

1. Open the browser and load a new tab.
2. Type in “chrome:flags” in the address bar and press “Enter”

   

3. Find the “Autoplay Policy” heading, click on the dropdown and select “Document User Activation is Required“.
   Note: There are a lot of options in those settings therefore, it is a bit difficult to find the Autoplay Policy one. However, you can press “Ctrl+F” and type in “Autoplay” and you will automatically be shown the option.

   

4. Once you select this setting none of the sites will play videos/audio automatically and you will have to manually press the play button in order to play videos or audio.
5. Open the site and check to see if the issue persists.

Solution 6: Reinstall audio and graphics driver

Sometimes when you install device drivers on your computer, some of the installation files might get corrupted due to a poor internet connection or any other reason. If updating your audio driver didn’t resolve this error, then reinstall the audio driver on your computer. It is always recommended to reinstall the graphics driver too. Following the steps given below and check if the error is rectified:

1. Press “Windows’ + “R” to open the Run prompt.
2. Type in “Devmgmt.msc” and press “Enter”.

   

3. In the device manager, expand the “Display Adapters” option and right-click on the “GPU Driver” that you are currently using.
4. Select the “Uninstall Device” option and follow the on-screen prompts to uninstall this driver from your computer.

   

5. Wait for the driver to be completely removed from your system by the setup.
6. Windows should now be switch to a basic display adapter from Microsoft that should keep your display up and running.
7. Navigate to the Nvidia or the AMD website depending upon which GPU you have on your computer and download the latest driver for your graphics card from their download directories.
8. Run the downloaded executables to install these drivers on your computer.
9. After successfully reinstalling the GPU drivers, we will now be reinstalling the audio drivers.
10. Press “Windows” + “R” to open Run, type in “Devmgmt.msc” and press “Enter” to launch the device management panel.
11. Inside this panel, double click on the “Sound, Video, and game Controllers” dropdown to expand it and right-click on the Sound Drivers that you are using.

    

12. Click on the “Uninstall Device” option to remove these drivers from your computer.
13. Restart your computer after doing this and Windows should automatically reinstall a basic version of the driver. If it doesn’t, try to install a sound driver yourself that sits well with the motherboard installed on your computer.
14.  Check to see if doing so fixes this issue on your computer.

Solution 7: Unplug Audio Hardware and Plug It Back

It might be possible that the correct audio driver for the output device might not be selected or if you have additional audio hardware, that could prevent your PC from streaming with Twitch. Hardware such as headphones or external speakers could be interfering with the stream.

Therefore, it is recommended to unplug all audio hardware connected to the computer and try to launch the stream. If the stream is working correctly without the audio hardware plugged in, try reconnecting the hardware and check to see if the stream keeps working normally.

Solution 8: Diagnosing Background Applications

This error might occur on twitch if there is an unwanted application running in the background, that provides audio feedback. There is a chance that some active media player is interfering with the playback service of the site or the browser and causing this issue. Therefore, follow the steps indexed below to close the background apps and check whether the twitch error 4000 still persists:

1. 1. Press “Windows” + “R” to launch the Run window.
   2. Type in “taskmgr” and then press “Enter” to run the task manager.

      

   3. In the Task Manager, click on the “Processes” tab at the top and a list of applications should be shown that are currently running on your computer.
   4. Check if any application is using an abnormal amount of resources on your computer and click on it.
   5. Click on “End Task” to prevent it from running on your computer.

      

   6. Similarly, click on the “Memory” and the “Disk” options one by one and eliminate all high usage applications.
   7. Check to see if doing so fixes the issue with the twitch stream

    

2. Performing the above steps should get rid of most of the third party applications that are running in the background. However, we also have to ensure that a system service or application isn’t interfering with the Twitch stream. Therefore, we will also be preventing that from running in the background.
   1. Press “Windows’ + “R” to launch the Run prompt.
   2. Type in “MSConfig” and press “Enter” to launch the Boot settings window.

      

   3. In this window, click on the “Services” option and then uncheck the “Hide all Microsoft Services” option.

      

   4. Click on the “Disable all” button to prevent these services from launching at startup.
   5. Now, click on the “Startup” tab and select the “Open Task Manager” option.

      

   6. In the task manager’s Startup tab, make sure to disable all applications from launching at startup.
   7. After that, save your changes and close out of both windows.
   8. Restart your computer and check to see if the stream works as it should.
   9. If it does, it means that a service or application was interfering with the proper functioning of the application. Therefore, you can start enabling these services and applications one by one and check which one makes the issue come back.
   10. After diagnosing the faulty service or application, you can either try to reinstall it or keep it disabled permanently.
