I’ve got a Librem 13 on which I’ve got Ubuntu 18.04 installed. Ever since I booted it up for the first time the built in microphone only generates white noise. Here’s a screenshot of it in Audacity (I guess you can imagine how it sounds):
My sound input settings look as follows (it’s in Dutch, but I guess it’s self explanatory):
As you can see in this screenshot there’s some sound, which is the white noise which I hear in other programs. I’ve tried in multiple programs (Audacity, Skype, etc), but the result is the same in all.
Does anybody know what the reason of this white noise could be? Is this a software or a hardware issue? Any way to debug this?
All tips are welcome!
