Teranex Mini Audio to SDI converter issues with AES

We just received and installed our Teranex Mini Audio to SDI 12G converter with the goal of taking the AES3 out of our dLive console to keep a digital audio signal throughout our broadcast.

First off I didn't realize you were required to have an SDI signal coming into the device. It's listed as a Audio to SDI converter, not embedder. After trying firmware updates and such and still getting no signal I decided to try feeding it a video signal. It suddenly started working. It sounded good for the first few seconds and then there was a noticeable digital distortion coming through the signal. We would reset the connections and it would sound great at first, then the sound would come back in. I have a dropbox link below so you can hear what I mean. If we turned the input down the volume of the sound would lower to. Completely turning the signal down turned the odd sound down too.

We did a TON of troubleshooting. Tried different video sources, I disabled the audio on the source of the SDI coming into the converter, , changed AES clockrates, etc. Then we switched everything over to analog connections and the audio sounded fine. We're at a loss for what this issue might be. Did we just get a bad unit?
