Having trouble as HW-T400 Samsung sound bar keeps dropping out ( fourth blue LED light flashes) have to keep disconnecting from power then it pairs straight away , does it every day. When it is working lip sync is awful with all media networks. I have read the using a digital audio lead may help have a port on the sound bar but can’t see one on the tv.
@Members_OkOWcm7: The AU7100K does feature a Optical port for digital audio, which requires an optical cable connection between the TV and soundbar. If you utilise this connection method, please ensure that you head to Settings > Sound > Sound Output > Optical on the TV itself. Let me know how you get on.
