So I recently received my new XPS 13, paid a large sum ($1,000) for the 8GB with i5. Either way it's a great laptop, and has a beautiful screen and design. I have one issue though that is causing me a lot of stress and hair pulling.
When I access any task that activates the built in microphone, the task stops responding. The webcam works fine though. So my common tasks like TeamSpeak and Skype just crash as soon as I try to do something that requires the mic. I have all the proper driver installed, and when I first got it, with the default settings Dell has installed (All the drivers were pre-added from what I saw) it had the same issue. I upgraded the OS for a clean slate, re-installed all the drivers and it is working great, audio is perfect etc. The microphone still is broken though. When I open the recording devices in the audio settings, the whole sound system crashes. But it does show the microphone as enabled and set as default device.
I have been destroying Google search trying to find an answer, and a few people have the same issue but no response on what causes it or how to fix it.
