Windows 10: Why is sound output muted when input is detected?

I'm trying to use a USB Sound Card to output a tone while looking for a sound input. I see that when the input function is selected, the output tone is muted. Is there some device configuration that is causing this?

Muted mic picking up sound in game

Hi JonPaul,



Thank you for writing to Microsoft Community Forums.



The issue could be because of the internal mic picking up sound even when the external device is pluuged in. If you have the RealTek HD Audi Manager installed on the machine, I would suggest you to try the steps listed below and check if it works for
you.

• Open RealTek HD Audio Manager and go to the
  Advanced tab.
  
• Check the boxes Separate all input jacks as independent input devices
  and Mute the internal output device, when external headphone is plugged in,
  and hit OK.
  
• Exit RealTek HD Audio Manager, restart the machine and see if the issue persists.
  

Regards,

 

Playback detecting Input Devices & Recording detecting Output Devices

Hello!

Today, I was playing SCP: Secret Laboratory. After I finished, I went and made tea. When I came back much later to play some more, I found that the in-game voice chat was not working for me; my microphone was not transmitting in-game.
Looking into my Steam settings, I found that all my input devices were actually my output devices, and all my output devices were actually input devices. I initially thought this was an issue with Steam, so I restarted Steam and my PC.
However, when the problem did not resolve, I looked to my sound settings and found that even in there, my playback devices detected inputs as outputs and recording devices detected outputs as inputs.

How am I able to fix this problem?

The VoiceMeeter inputs and outputs are from a sound managing device called VoiceMeeter Banana that I installed to allow for the creation of virtual line ins.

 

Microphone Detected but no sound input detected

- My PC has 2 3.5mm microphone jack inputs
- Upon plugging any (tested on other devices) microphones into these jacks, my pc detects that they have been plugged in

- However, when speaking, no sound input is detected

- I have tried ALL options mentioned in this thread Microphone detected but no input sound - Microsoft Community in 2018, the author of which appeared to have the same (unsolved) problem as I.
- Sound input is detected fine from USB microphones
