Hi I have recently puchased and set up QE75Q950R - picture is lovely and all is working fine. There seems to be one very minor issue - I have connected the TV to my soundbar (Panasonic All70T) using the ARC HDMI3 input. When setting up device it says there is no signal from this port but the sound is coming out fine from the soundbar and volume can be adjusted up or down with the Samsung remote.
But as it is not recognising the device on the port, the remote control cannot perform any other actions on the soundbar and there is no on screen info when you put the volume up or down.
Is there a way to ensure that the soundbar device is recognised on the HDMI3 port?
