Thanks for all the replies.
The cable guy had an optical cable plugged into the cable box then to the receiver (in addition to the HDMI connection) so I unplugged it from the cable box and into the optical out on the tv which then sent the audio signal from the tv to the receiver.
So for now...
I need some advice on how to connect my current older surround sound system with a newer smarttv so that I can have audio from the apps thru my system.
I’ve done a lot of reading but there’s an overwhelming amount of information not all of it consistent.
