I've tried three different Dells today and can't reproduce any such problem. The internal mic always restores correctly and working.
Tried both 17.10 and 16.04 but it sounds like you mean Unity where the dialog is "Unknown Audio Device". So that's either 16.04 or 17.04. And no I don't recall related bug reports. ** Changed in: unity-control-center (Ubuntu) Importance: Undecided => Low -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to unity-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1716359 Title: Unplugging headset with audio panel open mutes internal mic Status in unity-control-center package in Ubuntu: New Bug description: This bug was reported by our OEM team, I'm opening this public bug.
