Acer Aspire M5-481PT audio problems

This problem is driving me nuts.

 

I just got an Acer Aspire M5-481PT.

 

The audio wasn't working out of the box.  The error message I see when I mouse over the audio icon is: "No Audio Output Device is Installed."  I don't get audio from the onboard speakers and no audio from the headphone jack.

 

I tried updating the audio drivers and still no luck. 

 

I deleted the audio drivers and rebooted.  Again no luck.

 

But here is where things get interesting.  The audio works if I plug in a USB headset or HDMI cable.

 

I even re-installed the entire system from a flash drive.  Again, no luck.  Does anyone have any suggestions before I send this back to Acer?

 

I'm running Windows 8.

...in that case i think that the on board speaker is faulty...but try to install different operating system if nothing happen that's the time you will bring it to the acer service center...
