Windows 10: Mono Audio turns off by itself each time i close or restart my laptop

Tried all of the audio related common fixes and none of them work Did the usual, updated all drivers, etc. Didnt work either, this looks like a unique problem for me since i can't find anything online about it.

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

I find that if I set mono, then restart, then test as I posted, it's mono.

This suggests another snaglet in 2004/20H2.

Another option for you might be to use the bat file in the tutorial and run that at startup.

I've asked about 20H2 after that tutorial for you.

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.

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

I just tested as you suggested:

1. Pre-start state is MONO is ON
2. Start computer to Windows 10 20H2
3. Audio flow is in stereo mode (left and right channels separated from input to speaker)
4. Access ease of use > sound
5. Switch MONO to OFF
6. Audio flow is in stereo mode (left and right channels separated from input to speaker)
7. Switch MONO to ON
8. Audio flow is in mono mode (left and right channels combined from input to speaker)

This tells me that there is an inbuilt windows software process responsible for copying input to output, which is failing to check the MONO flag when it starts at start-up time.
