Hi, I cannot get the Comcast remote to operate the Playbar on my Vizio E60u-D3 TV. I am using an optical connection. I was able to set it up properly on the Samsung TV we had it connected previously. I can change the volume only with the Sonos S1 App and not the remote. Anyone have suggestions? Changed to Bitstream per their owners manual Here is what I did to the TV based on their owners manual.
“Digital Audio Out - Changes the type of processing for digital audio out
and HDMI ARC output when connected to a home theater audio system.
Select PCM or Bitstream. “
