Just received an Acer Aspire E1-572, but there is no sound

Today I received an Acer Aspire E1-572.  It works fine except there is absolutely no sound.  The speaker shows it as at 55 percent, and active.  I've fiddled around with it, but nothing appears out of order to account for this problem.  How do I get sound on this computer please?  Perhaps by installing a driver?  The operating system is Windows 8.  Device Manager shows under Audio Inputs and Output

Speakers

 

Both are updated Realtex High Definition Audio.  Under Sound, Video and Game Controllers, it says Realtex High Performance Audio again.
