Re: Audio in via HDMI on Buster with pulseaudio on Pi4?

No.
It is an HDMI output. It does not support Audio Return Channel (ARC) or any other mechanism for making it an input for any data (other than CEC and reading the EDID).

Check your monitor's manual for how it handles that microphone jack. USB sound card perhaps?

Re: CEC not working

Simply pressing the HOME button and navigating through the menus to [Settings] — [Watching TV] — [External inputs] — [HDMI CEC Settings] — [CEC] will turn on the HDMI CEC Settings. Turn on the HDMI CEC Settings on the device that is currently connected.
