Hiya! My mother's work recently gave me a pair of headphones (Jabra Evolve 30 II). When I use the 3.5 aux plug (without the desk button bit) it works fine, but no mic (my laptop has separated input and output ports), and when I try to use the USB port, I can select the headphones for speaker and mic. The mic works fine, however the speakers come out of the laptop speakers. I am running PopOS (Ubuntu) on a Samsung RF511.
Thanks in advance, and I hope you can reply soon!
