Internal microphone has stopped working on new HP Pavilion 15" laptop

I've had a new laptop for a few weeks, and all of a sudden the internal microphone (Microsoft Array) has stopped working. I suspect this may be due to a driver problem, but according to Windows 11, I have the latest drivers. The troubleshooter isn't able to identify the problem, and I've checked permissions in the privacy settings. This is proving to be a big problem when I have to use Skype or Zoom at work. Any ideas?

First, try the suggestions in this article. How to Fix It When a Laptop Microphone is Not Working

If none of those suggestions work, to prove whether it is a hardware or software problem, if you have access to one, the easiest way is to connect an external microphone and change your settings to use it as default. If an external mic works, it would point to it being a hardware problem with your built-in mic. Since the laptop is under warranty, I would contact HP and let them work it out.

You sure you did not just accidentally clicked the mute button on the keyboard? Sometimes it happens.
