Let us discuss them in detail.
1] Download and install Web Media Extensions
The absence of Opus Codec can be resolved by installing the Web Media Extension from the Microsoft Store. Media Extensions is a package that contains all the necessary codecs, including the Opus Codec, needed for playing voice notes in WhatsApp. These extensions support modern media audio formats like .opus and .ogg, commonly used for WhatsApp voice data.
By installing Web Media Extensions, you can make sure that your system can handle various audio formats, which should help fix any errors when playing voice notes. To do so, follow the steps mentioned below.
- Open the Microsoft Store by searching it out of the Start Menu.
- Search for “Web Media Extension”.
- Then click on Install or Get to download and install the extension.
If you don’t see an Install or Get button, instead it says“Open”, you can skip this solution as Media Extension is already installed on your computer. After installing the extension, check if the issue is resolved.
2] Disconnect and reconnect your headphones
More often than not, users who were trying to listen to the voice notes on their headphones encounter this issue. So, in order to resolve it, we recommend you disconnect your headphones, whether it is wired or wireless, reboot your computer, and then connect them back. Finally, check if the issue is resolved.
3] Configure Audio Enhancement
Audio enhancement on Windows refers to a set of features designed to improve the sound quality of your audio output. However, at times they can be counterintuitive by interfering with some of the audio functionality. So, we are going to change the state of Audio Enhancement and see if that helps. To do so, follow the steps mentioned below.
- Open Control Panel.
- Set View by to Large icons.
- Click on Sound.
- Go to Recording, right-click on your microphone, and select Properties.
- Click on the Advanced tab, now, tick Enable audio enhancement if it’s unticked, and untick it, if it’s already checked.
Finally, check if the issue is resolved.
4] Reset Volume Mixer Settings
You may encounter this issue if the Volume Mixer, which manages audio for each application, is misconfigured. Resetting the Windows Mixer can fix incorrect audio configurations that may prevent apps like WhatsApp from accessing audio channels and codecs, allowing voice messages to play without interruptions or errors. To reset the Volume Mixer, you can follow the steps mentioned below.
- Open Settings by Win + I.
- Go to System and then click on Sound.
- From the Advanced section, click on Volume mixer.
- Scroll down, and click on Reset associated with Reset sound devices and volumes for all apps to the recommended default.
This might take a few seconds, and once done, you can open WhatsApp and see if the issue is resolved.
