I will guide you How to fix the error “You must have the Opus codec installed” on WhatsApp
Problems with voice memo playback like the “You must have an Opus codec installed” error are common, which implies that the Opus codec, which is responsible for decoding and encoding, is not present on the system. However, this is not the only reason for the problem; other factors such as disabled UAC or a glitch in the Windows mixer can also cause it.How to fix the error “You must have the Opus codec installed” on WhatsApp
Problems with voice memo playback like the “You must have an Opus codec installed” error are common, which implies that the Opus codec, which is responsible for decoding and encoding, is not present on the system. However, this is not the only reason for the problem; other factors such as disabled UAC or a glitch in the Windows mixer can also cause it.
After discussing the causes, the most important thing is to ensure that the Opus codec is present on the system. This error message will be generated because WhatsApp voice memos cannot be encoded or decoded if it is missing.
We will look at the solutions to this problem now that you understand the causes. But before we proceed, try restarting your computer or ending the WhatsApp process in Task Manager and then opening the WhatsApp app again.
1. Download web media extensions
Since the error message says “You must have an Opus codec installed,” you should start troubleshooting the problem by installing the Opus codec. If you want to be able to use WhatsApp to create voice notes, you will need the Media Extensions package, which contains all the necessary codes (including the Opus codec).
Current media audio formats like .opus and .ogg, which are used for WhatsApp voice data, are supported by these extensions. While installing Web Media Extensions, you make sure that your system can handle multiple audio formats, which should fix the error when playing voice notes.
- Select Microsoft Store by clicking on the "Start" menu.
- To find Web Media Extensions, launch the Microsoft Store.
- Click Install after choosing Web Media Extensions.
- Check if this might resolve the error after doing so.
2. Enable User Account Control (UAC).
This issue could also be caused by you previously disabling UAC (User Account Control) and forgetting to enable it again. Many users have mentioned that turning on UAC somehow resolves issues with WhatsApp voice notes, although UAC should not be related to the problem. So, you need to make sure that UAC is authorized by following these steps.
- To open Windows Search, press Win + S.
- To open the “Change User Account Control” settings, type UAC and press Enter.
- Listen to Notify me only when apps try to make changes to my computer in the forward control.
- To save the settings, click OK.
- After you have done this, try to play WhatsApp voice notes to see if the error is fixed.
Step
3: Restore Windows Mixer
The audio for each application is managed by Windows Mixer. Sometimes, applications cannot access or play audio correctly due to incorrect audio settings. By re-enabling Windows Mixer, you can restore the default audio settings. This ensures that WhatsApp can access audio channels and codes, including the Opus codec, which allows voice messages to be played without interruptions or errors.
- To restore Windows Mixer, click on the sound icon at the bottom right and select Open Mixer Volume.
- To return Mixer to its default settings, click on the Reset button.
- After you have done this, check if the error is fixed by playing WhatsApp voice notes.
Finally, try uninstalling WhatsApp and Media Web Extensions if none of the above solutions have worked. After that, restart your computer and reinstall WhatsApp along with Media Web Extensions to fix the error.
