I do have to ask the obvious,<br>
Are you sure you are testing the output correctly ?<br>
I believe these FLOAT and switch to ground when active.<br>
Just like a parallel port.Don't use them so I don't know for sure.<br>
So you need to check continuity between ground and the pin in question for activity.<br>

Hi Stephen,<br>
<br>
While the CM108/CM119 audio chips found in URI's are powered from the +5V<br>
USB source, they contain an internal +3.3V regulator and are internally<br>
completely 3.3V logic....So, you'll never see more than +3.3V as a<br>
logic "high" level coming from the GPIO pins.<br>
