This requires me to disable the auto-mute feature. I haven't rebooted my system yet to see if this is permanent. But the UI doesn't show the heaphones at all and only sends sound through the main speakers of the laptop. ➜ ~ lspci -nnk | grep -i -A7 audio 00:1f.3 Audio device [0403]: Intel Corporation Device [8086:a348] (rev 10) Subsystem: Razer USA Ltd.

If I reboot or close pavucontrol, everything is back to the original state and only the speakers work. Additional Information: ➜ ~ lsb_release -rd Description: Ubuntu 18.04.1 LTS Release: 18.04 What I expect to happen: When I plug in my headphones, Ubuntu and the UI should see them and automatically redirect all sound through them.
