Comment 11 for bug 1924685

I've connected USB sound card "Sound Blaster Play! 3" and Headset Microphone works just great. So headset microphone on XPS 9700 doesn't work due problem with drivers. I suspect that Dell put some non standard solution for switching between Internal Microphone and Headset Microphone because when I deleted from Windows 10 external utility called Max Audio Windows stopped switching to headset microphone whenever I plug headphones even when I select it manually. After reinstall of Max Audio it started to work as expected. Does anyone have clue to this annoying problem with Headset Microphone?
