Windows 10: my microphone stopped appearing on input devices out of nowhere

Out of nowhere my microphone stopped showing on every app such as discord Xbox game bar etc. I cant get it to work but on this device but on every other device it works just fine. any fixes I've tried restarting my pc and making sure my microphone is accessible to apps.

Sennheiser GSP 350. Microphone stops working when I open any game

Wow, ok. I think I've fixed it by accident while fiddling around.

It appears to be the Realtek audio being the issue here. I don't use my onboard sound card as my headset is a USB headset only and my speakers are plugged into an ASUS sound card.

Step by step fix:

• I went into recording devices
• I enabled STEREO MIX (Realtek High Definition Audio)
• Then I set that Stereo Mix as the DEFAULT DEVICE (At this point it took over both input and output devices without my permission )
• Then set my Sennheiser headset as default recording and playback devices in their respective windows even though they both still said they were the default devices when they weren't

Headset microphone is currently functioning while in game now. I'll update the thread if it goes again. Should I completely disable Realtek audio??? Or will windows just force it to work again?

 

External microphone not showing in the Recording tab

My Windows 10 laptop is not recognizing any external microphones. I have two headsets: a Bluetooth one and one for an audio jack. Both headsets work correctly on other devices. When I connect the headsets to my computer, I can hear audio, but the microphones
do not work.

Here are the steps I've taken so far:

• Updated drivers (they were already up to date)
• From Sound Settings, headsets do not appear as options for the input device
• Ran the microphone troubleshooter - headsets do not appear as options
• From Control Panel > Sound > Recording, headsets do not appear as options. I have selected the disabled and disconnected devices options.
• From Microphone Privacy, all apps have access to the microphone.
  

That's everything I found online to fix this problem. Any suggestions?

 

All usb microphone inputs not working


So both my adapter for xlr to 3.5mm jack input and my newly purchased usb microphone are not recognised. I've tried updating the drivers, using different usb ports, uninstalling the drivers and letting windows do it manually. Every time though, it's listed as having issue's in device manager... Can some help?
