I have a hearing deficit and use a Sennheiser Assistive Hearing set (transmitter and receiver) while watching TV which normally plugs into the headphones port with a standard 3.5mm plug. My newly purchased UN55NU7100 does not have a dedicated headphones port. The "Connection Guide" on the TV explicitly mentions the ability to choose between "Optical and Audio Out" illustrating the different cable connectors for each. Damned if I can find something that works using one of the two  coloured ports which are labelled AV In and Component in, nor find any other port. The manual, such as it is, is a joke. Am I missing something simple and obvious (complicated and not obvious?)? Grateful for your help with this.
