Hi veda priya,
Thanks for sharing the details. To help narrow down whether this is a Windows issue, an app-specific problem or a microphone fault, could you please try these additional checks?
First, open Sound Recorder, record a short message and play it back. If your voice is recorded normally, the microphone is working in Windows, and the issue is likely limited to the app or website you use for voice notes.
If you are using a website, check its browser permissions and make sure microphone access is set to Allow. Please also close any other calling, meeting or recording apps that might be using the microphone, then reopen the affected app and test again.
You can also press Win + R, type services.msc and press Enter. Restart Windows Audio and Windows Audio Endpoint Builder, then check the microphone again.
If possible, try another headset or external microphone. This can help confirm whether the issue is limited to the laptop’s built-in microphone.
Finally, please press Win + R, type winver and press Enter. Let me know the Windows version and OS build shown, whether Sound Recorder captures your voice and whether the problem occurs in every app or only the app used for voice notes.
I hope this helps narrow down the cause.
