Answer 1

Have you tried to search this forum? There seem to be several similar issues with front panel and 16.04.

This one shows GUI solution Front audio is not working on 16.04

And this one shows terminal solution Front Audio Panel Issue

Insert your head phones and in Terminal run the command alsamixer, and then switch the volume bar for headphone by pressing M.

If the sound appears and everything goes smooth then you can save the result of alsamixer by running the command

sudo alsactl store

This should save alsamixer configurations to /etc/asound.state which gets loaded every startup.

Answer 2

What helped for me was to run alsamixer with headphones in. Then moving right to the column marked "Auto-Mute mode" and pressing down to disable it.

Headphones then worked.

I also ran sudo alsactl store for good luck.

Seems to have worked.
