Question

Why is the microphone on my headset not recognized on my MEDION notebook or PC, even though the headset is displayed as Realtek HS Audio 2nd Output?

Answer

The problem may be due to the different assignments of the audio jacks. MEDION computers usually use the CTIA standard, while some headsets use the OMTP standard. This means that the sound works, but the microphone is not recognized.
The solution is to use a suitable adapter or splitter (CTIA / OMTP adapter or headset splitter for separate headphone and microphone connections). This will ensure that the microphone is recognized correctly and works properly.
