Input audio not working, headset or internal mic

The only sound is this low buzzing sound no matter how loud I talk. I would appreciate any help :confused:

Welcome to the community @shangli

Fedora F32 is not supported anymore. F33 will also soon be unsupported ( apr. 5 weeks )

Upgrading to a new release of Fedora :: Fedora Docs

You will see that the audio works better with the newer version.
