I loaded Mint Cin 18.2 and everything works except the speaker sound, when you run the test they produce no sound, the mic works fine.
 

I loaded Mint Cinnamon 18.2 and now the speakers don't work, any suggestions?

Raise up all of the columns and make sure they are not muted.

(mm) means muted and (oo) means not muted.

Run this command to find out what sound card you have:-

Also what is the output of lspci?
