I have an HDMI cable connecting my Panasonic Home Theater surround sound system, model # SC-PT650. Link to manual: ftp://ftp.panasonic.com/hometheater/om/sc-pt650_en_om.pdf

There is no sound coming from the home theater when watching TV, which is hooked up to a cable box. There is sound when a dvd is watched. This is an older home theater system and there is no optical cable feature. There is an optical cable feature the TV, which is a new Sharp, model # LC-50LBU591U. Link to manual: https://www.sharptvusa.com/sites/default/files/2017-08/Sharp%20LC-43_50_55_65LBU591U_C_17-0066_MAN_V1_EN_Final_lr_0.pdf

Any help would be appreciated!
 
Thank you for the links.
You need to have HDMI-ARC in both the TV and the HTS. That one is too old to have ARC. The HDMI output is for DVD playback only.
The only input the HTS supports is analog audio via the RCA input jacks. You are fortunate that the TV has a line out jack next to the USB port (page 34 of the manual). It uses a 3.5mm stereo headphone plug so you need a cable with that on one end and 2 RCA jacks on the other. There are also adapters if you already have a cable that only plugs in at one end. That might have a male 3.5mm to 2 RCA females or two RCA males to 1 3.5mm female jack.
