Sound stopped coming from speakers after using HDMI cable to watch a movie in tv

Asked by José Pereira on 2016-05-12

I had no problems with Ubuntu 16.04 LTS until yesterday. For the first time, I plugged my laptop to the tv using a HDMI cable and watched a movie with my girlfriend. Today, when I woke up and turned on the pc I was surprised because no sound is coming from the speakers.
I tried doing everything advised on the Ubuntu forums after searching for the same problem in google and nothing worked. I also followed the advice in the troubleshooting guide and still not working.

Strangely, sound is working in the guest account and also via hdmi (on my admin account) and I also hear the drum sound when ubuntu main menu starts up.

My terminal output after following the advice on sound troubleshooting is the following:
