Hi Tobias. My name is Lester, and I am an Independent Advisor. I'm sorry that you are experiencing this issue. I'd be more than happy to assist you.
Do you remember making any changes such as a Windows update or hardware modification before experiencing the issue? Have you already tried to download and install the latest available audio driver from your PC manufacturer's website? Make sure that it is compatible with your PC.
