Comment 39 for bug 1866194

I have a similar problem on my Dell XPS 13 - if I boot the laptop with the headphones (3.5mm) plugged in, then it essentially disabled the 3.5mm headphone jack - nothing I've tried re-enabled it again (eg unplugging/replugging the headphone, all the settings, etc). Only a reboot without the headphones plugged in and plugging them in after logging in, fixes the problem.
I don't have this problem on my Lenovo T480s.
Perhaps this is a different problem?
