Tone Board Playing One Channel Only

[mpbrog61]

I received a new Tone Board today but it is only playing through one channel. I have swapped cables and tried playing files from a Pi or PC and get the same result. Has anyone had the same issue or is it an issue with the board itself?

Tone Board Only Playing One Channel

I recently purchased a TB but it is only playing one channel. I have connected it to a PC and Pi with the same result. It is not the amp or cables. I can play stereo using a Pi with a HiFiBerry Dac+ Pro connected. The firmware has been updated but no change. Is there anything else I can try or should I send it back for a replacement?
