I recently installed Ubuntu 16.04 and I'm having a problem with my audio device.
*The internal mic is working properly
*The external output (headphones) is working properly too.
*But the internal speakers doesn't work.
I tried on the live version of 16.04 and I had the same issue.
Information of my laptop:
lspci -v:

Attached you can see the alsamixer configuration which shows the speaker
volume. In capture view the audio is also in 100%
I have no idea how to solve it. I used the same laptop with 14.04LTS
without this problem.
