I noticed not a long while ago, that if I tried to listen to music while chatting with other people on Discord, TeamSpeak3 or Skype, they could hear my Desktopaudio. I'm Using a headset with two 3,5mm jacks. Also other Applications like Audacity, OBS and even the Windows Mixer are recording desktop audio through the microphone.
But after trying several hours to seperate the audio I noticed these things:
- The Microphone picks up the desktop audio regardless which soundcard is used for Input and Output
- I tried to record the desktop audio via the mic, while turning off the microphone via hardware, it sounds like really heavy compressed audio with a low volume compared to the clear audio a microphone would provide.
- Muting the Microphone on the software side mutes it completly.
- Stereomix is disabled
- Front and Rear Outputs are seperated in the software
- I tested this on 3 Computers, two with Asus Boards and a Gigabyte Board, one of them is freshly installed with Standardsoftware I use
- Someone told me it is caused by Discord (if Browsers, Office and Standardsoftware excluded, this was the only software installed that is used across all systems), but have no real evidence yet, because uninstalling discord and resetting/updating drivers had no effect and I wanted to be reinstalling Windows on those machines as my last solution
- Tested Machines were Windows 10 and Windows 7
- Also tried a seperate Microphone and Headphone solution but ended up getting the same results
For those who need a little bit more technical Information:
External Soundcard (until testing not used): included USB card from the Sennheiser PC 363D, Sennheiser 3D G4ME1, only Windows 10 Plug and Play Drivers installed (not the complete Sennheiser drivers)

- System 2: ASUS ROG Maximus IX Hero, Windows 10, no Sonic Studio installed and freshly installed system, no configuration done up to this point
