Razer Tiamat 7.1 v1 - Connecting Speakers to Audio Control Unit

Hi Everyone, I have a Razer Tiamat 7.1 v1 and recently moved. I no-longer have the connector to the Audio control unit that allows you to use the control unit to control your speakers and the headset. Is there a way to purchase the cable that plugs into the Audio Control Unit? I asked Razer help and they said no - so I figured I would ask here. Does anyone know how I can purchase this cable featured in this video? https://www.youtube.com/watch?v=-YTubozx3zs If I cannot purchase this cable - what are my options for getting speakers and this headset to work? I really dont want to deal with plugging and un-plugging in speakers and headsets to get my PC to play both. Considering the plug in my PC uses 7.1 jack to my headset. This is an ultimate deal breaker and will force me to just not use these products anymore. Any help / advice is greatly appreciated. Thanks!
