Windows 10: What does 'turn on mono audio' do? More louder sound? What's the difference?

Hi, please tell me what 'turn on mono audio' does in Windows 10.

:)

 

Mono audio (ease of access) plus Listen to Microphone (audio control)

I wish to have my Windows 10 (20H2) machine listen to microphone (relay audio from sound input device to sound output device) and be in Mono audio mode (combine left and right input sound streams and send the combined result to both left and right output sound stream) at start-up.

The "Turn on Mono" setting does not appear to take effect until after an (any?) application using windows sound is started. The "listen to microphone" setting IS in effect at start-up (however, the audio flow is still stereo, which is not intended.)

Here is the step-by-step:

1. Start Windows 10, no audio-based application running
2. Ease of Access > Audio > Turn on Mono
3. Sound Control Panel > Recording > (double click on) Microphone > Listen > [x] Listen to this Device

4. Reboot.

5. At this point, the "Turn on Mono" setting does not appear to be in effect (left and right audio channels are still distinct)

6. Start (any) windows sound application

7. At this point, the "Turn on Mono" setting DOES appear to be in effect (left and right channels are merged at input, and the merged audio is presented to both left and right audio outputs)

8. Stop the windows sound application

9. At this point, the "Turn on Mono" setting DOES appear to be in effect (left and right channels are merged at input, and the merged audio is presented to both left and right audio outputs)

Repeatable beginning at step 4.

I imagine this is not intended behavior, and I'm wondering if it's an oversight in Windows 10?

Thanks for any advice or attempts to duplicate this sequence.

Accessablility Question: Mono Audio

Please, I don't think it's too much to ask for mono audio. My stupid phone can do mono audio with a simple slider, I'm half-deaf and it's just frustrating not being able to hear music or videos the way they're supposed to sound. I know the demand for this
is super small, but I'd be super appreciative if some attention could be given to it.
