Receiver

I use optical in both locations.  Would appreciate the other box (XG2V2-P )  As mentioned, The day after I noticed I couldn't use the optical , I went back to Comcast and asked if I could switch boxes and was told no.  I just switched from DISH to Xfinity last week ( 1000 down and 200+ TV Channels ) .  Any help would be appreciated.  Thank you in advance.

If needed, you can use something like this:

Thank you Andy---looks promising.

Andy,  can you explain the way to hook that up from cable box or tv to the sounbar?  I have no HDMI (ARC ) or Optical input on my TV....only the soundbar.   Thank you.

Thank you .  I phone Comcast and explained the situation.  The lady I spoke with could not understand  why they would not swap boxes at my local service center. Any rate,  she is sending one to me (XG2V2-P ) at an additional cost of $5 monthly.  Thank you very much for our reply.

Case closed.

Hello John7336. Thanks for visiting and posting on our Forum. I can assist with getting a replacement box ordered so you can swap your box to a unit that has an optical audio connector. Please send me a private message and include your full name and service address so I can get started.  

adding, is this a very old sound bar? Optical Tos-link cable connections are deprecated older and limited technology.  Do you have the model number and brand of the soundbar?

your model has an ARC (audio return channel) HDMI connector. try just connecting the set top box to the TV's HDMI 1 or HDMI 2 port. then connect an HDMI cable from the TVs ARC HDMI port to your sound bar's ARC HDMI jack.
