QC 35 ii Mic will fail in Skype calls after ~90 seconds.
as mentioned in the title, I'm having issues with QC 35 ii headphones (connected via Bluetooth) during Skype calls on my PC. It all works fine for around 90 seconds. Then Skype will tell me, that there's a problem with my microphone and I should switch to another microphone, update my drivers or restart my computer. While I'm still able to hear others, they cannot hear me. I already tried all of the suggested options multiple times, even reinstalled Skype twice and updated the firmware of my headphones. This problem does not occur during Skype calls on my Microsoft Surface though. I'm aware that this problem is more likely to be caused by Skype and/or my PC audio device (Realtek Onboard Audio; Driver Version 22.214.171.12491) than the headphones. However, I already reached out to the Microsoft customer support hoping that anybody there could help me (which they couldn't). So this is basically my last shot at this before getting an external mic or another pair of headphones.
Has anybody experienced similar problems??
Best regards and thanks for your support
