I just purchased two of these Acer monitors.  I understand from calling Acer that this particular part number (UM....) does have speakers, although I have not taken it apart to verify.
I also purchased a new Mac Mini and plugged both monitors in: 1. using the HDMI port to HDMI connection to back of one of the monitors and 2. using the HDMI to thunderbolt connection to the mini.
I can't get sound to come through either of the speakers on the monitors.  When I go to the sound preferences option on my Mac, I can see the two monitors, but anything available to modify is all greyed out.  I called and talked to both an Acer and Apple rep and neither were able to help me.
Anyone else out there experienced the same problem OR have a solution?  It would be much appreciated.  Thanks.
