Hi there!
Aside from the steps above, you can also try checking on your system settings itself if you have a Microphone available. For Windows 11:
Press Win + I → Settings
- Go to System → Sound
- Scroll to Input
If a microphone exists: You’ll see something like Microphone (Realtek Audio), Internal Mic, or Microphone Array. You’ll see “No input devices found” if you don't have any microphone available then.
Aside from that, you can try to record yourself and talk near your device. If the input level bar moves, the mic is present and working.
I hope this helps. Please note that this is a public forum, I will be responding you in short period of time and regret for a delay in response. As I am merely a fellow user trying to provide insight and information that may be helpful to others. Thanks!
