Windows 10: Headset microphone suddenly stopped working

My current desktop is a Dell Optiplex 3020, I use a Sennheiser GSP 300 headset and have been using it for around 5 months now. I mostly play games where communication is really needed, when suddenly the microphone stopped working, I've tried listening to what the microphone actually picks up, all it picks up is static noise and whenever I'm ingame and I try to use my mic, it picks up game audio and just repeats it all over again.

I've tried troubleshooting the problem and using it on other multiple devices, the microphone and headset both work just fine. Then I've concluded that the issue is from the computer itself, not the headset. I've reinstalled drivers about 4 times which are all different versions, nothing works. Checked in Control Panel and settings and everything is what it's supposed to be. I mainly use the front panel for my cables but even the back panel ports give me the same issue. And one thing the problem could be from the input/mic cable as well. I've tried to use the splitter that came with the headset itself, but all it says in Control Panel is that the microphone isn't plugged in. I've had this problem for about 2 months now and it's been tough.

Microphone suddenly stopped working

My microphone is still not working. I even checked the BIOS as someone had suggested but there is no listing for the microphone in there.

 

Microphone Suddenly Stopped Working

Hello, my microphone on my headset suddenly stopped working when I logged onto my computer. My audio is fine but my mic isn't working on my pc. I tried plugging in my headset to my phone and it works fine on there but not on the computer. Both jacks are
in their correct ports as well. I didn't do anything to my mic, it just wasn't working when I logged on today.

 

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?
