Fix 7: Set your audio device as the default device

If you’re connecting to an audio device such as headphones or speakers, you need to set that device as default.

Here’s how to do this:

1) In the search box on the taskbar, type control panel and select it from the results

open control panel set the audio device as the default device

2) Make sure you’ve chosen Large icons as the View by option. Then select Sound.

3) Under the Playback tab, right-click on your audio device and select Set as Default Device. Then click OK.

After applying the changes, reload the streaming page and check if the issue persists.


Fix 8: Update your audio and graphics drivers

If you’ve set your audio device as the default device but the error code still appears, you should try updating your drivers, especially audio and graphics drivers. There is a possibility that some of your installation files for the device drivers get corrupted.

Here are two options you can take to update your drivers: manually or automatically.

Option 1: Manually update your drivers

To manually update your audio and graphics drivers, you need to navigate to the official websites and download the correct drivers compatible with your system.

Here are some main manufacturers for audio and graphics drivers. Simply click on the links based on your own need and follow the on-screen instructions to download and install the correct drivers.

Audio drivers

Realtek

Graphics drivers

AMD
NVIDIA
Intel

Option 2: Automatically update your drivers (recommended)

If you update the drivers on your own, you might risk downloading the wrong versions. So if you don’t feel like doing it, we recommend you use Driver Easy. It’s a useful tool that detects, downloads, and installs the correct drivers for your computer. With Driver Easy, updating drivers becomes quite easy.

You can follow the steps below:

1) Download and install Driver Easy.

2) Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.

3) Click the Update button next to the video driver to automatically download the correct version of that driver, then you can manually install it (you can do this with the FREE version).

OR

Click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system. (This requires the Pro version with full support and a 30-day money-back guarantee and You’ll be prompted to upgrade when you click Update All.)

4) Restart your computer and load the streaming to check if the error still appears. If updating the drivers doesn’t resolve the issue, move on to the next fix.


Fix 9: Remove audio hardware

If neither setting your audio device as the default device nor updating drivers help solve the problem, you should remove your audio hardware. Hardware such as headphones or external speakers could be interfering with your streaming. In order to prevent the conflict, you should remove the audio hardware and try loading the stream again. If the error disappears, you can plug it back.

Fix 10: Switch to Twitch desktop app

If none of the methods listed above work for you, then you should use the Twitch desktop app. Compared to the web version, the Twitch desktop app has proved to have better performance and it brings better responsiveness.
