Purchased a new Ultra w/the Private Listening remote. Setup is as follows:
Roku->TV via HDMI, ARC control enabled
TV optical audio output -> Sound Bar.
When I plug in headphones to the remote, the sound bar is muted, and a headphone icon appears on the display, and allows me to change the volume. However no audio is directed out the headphone jack on remote.
Is there any reason this should not work? In the audio section of Roku setup, all settings (DTS, Stereo, etc) are all set to factory default 'Auto'
