Solution 1

Try this answer. Run these commands in the terminal:

sudo apt-get update && sudo apt-get upgrade
echo options snd-hda-intel model=auto | sudo tee -a /etc/modprobe.d/alsa-base.conf

Check all mutes and unmute them through:

sudo alsamixer

Then run:

shutdown -h now

Solution 2

sudo apt-get purge pulseaudio
sudo apt-get clean && sudo apt-get autoremove

Reboot. Open a terminal again and type (ignore any errors with the rm command):

rm -r ~/.pulse ~/.asound* ~/.pulse-cookie ~/.config/pulse
sudo apt-get install pulseaudio

Solution 3

You can try this:

sudo apt-get purge pulseaudio
sudo apt-get clean && sudo apt-get autoremove

reboot as:

sudo init 6

The open your terminal and:

sudo apt-get install pulseaudio

Plug your earphone and start some .mp3's

This is essentially the same as the answer of Silas Miranda. Could you develop why you think your approach is better?

Thanks. Worked like a charm on my inspiron 15 5000 series.

You'd start the pulseaudio daemon with this command. As you can see in the picture the sound dialog opens - so pulseaudio runs already
