Hello I am running Xubuntu 16.04 (kernal is 4.13.0-32-generic) on an Asus laptop, after unplugging headphones the speakers are not working. I have searched a lot of old posts and found no explanation.
Looking at Sound Settings, on the output devices tab, headphones are marked as plugged in, when they are not, and speakers marked as unavailable.
I would be grateful for any help and suggestions with this problem.
Thanks in advance, PC.
