URX-P03D no sound on output 1 or 2.

I recently got a URX-P03D with two UTX-B40s. I can get sound from the headphone output, but I can't get sound from output one or two. I am using the included cables and I have tried every assign setting. Out1, out2, out1/2. When plugging into headphones from the output not the phones port, I get no sound. But plugged into my ZV-E1 via 3.5mm I see hi noise levels. Plugging headphones in to the output on the zv-e1 I got a sound like a terrible digital helicopter, something like you might expect to hear from a PC speaker back in the day. For now I am going to plug into the headphone output on the URX-P03D and use that. How can I fix this? Also, upgrading to a URX-P41D is on my list. Thanks.
