Hey Copilot Voice Function is not working

I am trying to use the "Hey, Copilot" feature in the Copilot app on my PC. It is not working because the voice assistant does not open when I say the wake phrase.

I have already contacted technical support, and after going through all the troubleshooting steps, we were unable to find a solution.

My microphone is working perfectly because if I launch the voice assistant manually, I can have a voice conversation without any issues.

Microsoft Copilot version: 150.0.4078.96 (64-bit)

Windows 11 installed

"Hey, Copilot" is enabled

Mic permissions are enabled

Manual voice conversations work correctly

Reinstalled Copilot and restarted the PC

Issue: Saying "Hey, Copilot" does not activate voice mode.
