Razer Nommo AUX - 1 Speaker Working

Hello, My Razer Nommo Speakers are connected to my PC by USB and the Audio works fine out of both speakers. The AUX cable is connected to my Samsung Monitor so my work MAC and Xbox can both output audio to the Nommo Speakers. However, then using the AUX, only the Left speaker is outputting the audio. Which is surprising to me because the AUX plugs into the right speaker. I've checked all software is up to date on the PC and there are no hidden settings I can see to correct the audio output. Do I lose the Left/Right function using AUX? Is there a better way I should be connecting my Xbox and MAC to the Nommo speakers? All help is greatly appreciated Katie
