"Since Sunday, my WhatsApp has had a problem. My voice notes automatically become an error when I send them, and when I record, the line is straight silent. When people call me, I can hear them, but they can't hear me. I checked my microphone settings on my iphone but it's enabled, got plenty of storage too. Even tried to delete and reinstall the app,p but it still isn't working. Can someone please tell me what the problem is with my whatsapp and how to fix it?"

WhatsApp voice messages make conversations faster and easier, allowing users to send audio instead of typing long texts. However, many users may encounter the issue of voice messages not working on WhatsApp, such as voice messages not playing, failing to record, or not being sent successfully.
This problem can affect both Android and iPhone users and may happen in different situations. Before trying random fixes, it is important to identify what type of issue you are experiencing. In this guide, we will explain the common reasons why WhatsApp voice messages stop working and provide step-by-step solutions to help you restore normal audio messaging.

If your WhatsApp voice message is not working, the problem may come from different parts of the app or your device. Common causes include:

If the sound returns, replace it with a protector that does not cover the sensor area.

Connected Bluetooth devices may redirect WhatsApp voice message audio to headphones, earbuds, or speakers instead of your phone.
