Hi
I have a new inspiron 7559 (about a month old), windows 10, everything updated, no interfering antivirus, etc.
Since the start, I've been unable to use my external mic. I have a headset with a microphone, on one of those mic+speaker combined 3.5mm plugs. When I plug it in, the sound system detects my headset just fine and routes sound to it.
It kinda bugs me that the system doesn't show the individual devices to windows for finer control, and instead just reports a single audio device, but ok fine, I can understand that from a technical POV.
The real problem though is that no matter what I do, only the built-in microphone is used, never my external one on the 3.5mm plug. It doesn't show up as a device, there's no setting for it in the sound system, and the system doesn't switch to it automatically when it's plugged in. I just cannot get any sound from it (no, it isn't broken).
Any help would be much appreciated, thanks.
