I can understand how confusing it can be sometimes when a seemingly simple setup doesn't end up working as expected. Nonetheless, I have spoken to one of my Home Theater guys and he advised me of the following:
"The composite inputs that hes plugging that stereo into is an Input, not an audio output. When he plugs it into the cable box, those composite inputs are probably intended for audio. My recommendation would be to find out what the audio output is for that TV (probably digital optical) and to connect the stereo to the TV that way. This will ensure that no matter what input hes watching, all of the audio is sent directly to the stereo."
That being said, I, too, have my TV connected to my home sound system via digital optical and it works great. Any items I plug into the TV send the audio straight to my audio system. I would suggest trying this out as it seems the composite route is not a viable option for your setup. Feel free to let me know what other questions you may have!

What’s the model number of your LG “boom box”, Toshibia TV, and which box do you have from your cable provider? We’d be happy to double check which connections should be correct given those details.

While reviewing the manuals it sounds like you do have things connected correctly, however, you may need to change a few of the settings within the TVs menu further.
I’d recommend trying to change the following settings: Go to > Picture > Advanced Settings > HDMI Input Mode > Try Mode (1.4) or (2.0). Other customers that have had issues with HDMI 1’s ARC abilities have used those preferences to resolve similar issues. Let us know if that works for you or if you continue to have an issue.

Not to Hijack JoeyFV's post but I am having very similar issues.
I had an LG flat screen tv that just went black with no image but sound on Sunday 04/28/2019 so I bought the Toshiba FireTV (the exact same TV as JoeyFV) on the same day my LG died.
I have an Arris DCX3510-M Cable box from Spectrum/Charter/Time Warner. I have a Sony FM Stereo/FM-Am Reciever STR-D350Z. I am running a Gefen TV Digital Audio to Analog Adapter GTV-DIGAUD-2-AAUD. The LG had an Optical output that I plugged into the Gefen TV adapter and then into my Sony Reciever. I used the Sony reciever for my all my audio. I had HDMI's plugged into the TV from my cable box and my Sony BluRay. Everything was working no problems but the LG TV died.
So I bought the Toshiba just like JoeyFV. Plugged the HDMI cord from my cable box into the HDMI 1 port in the back of the Toshiba, Plugged in the Optical Audio cord, Plugged in the BluRay player into HDMI 2.
No sound through the Sony reciever. Nothing. Dead. When using the cable box. The BluRay player would play sound. But not today.
So I am trying to follow your most recent instructions, "I’d recommend trying to change the following settings: Go to > Picture > Advanced Settings > HDMI Input Mode > Try Mode (1.4) or (2.0)" Well my Toshiba does not have those pathways. First there is no just "Picture", there is a Display & Sounds that I found a Picture Settings> HDMI1 or HDMI2 or HDMI3 or Composite or Apps & Video. Not Advanced Settings. So I choose HDMI1 another menu opens and it is Picture Mode. That does have an Advanced Settings option but not what you have listed, here is what is listed for me: White Balance, Mid Lumiance Gamma, Dynamic Backlight, Dynamic Contrast, MPEG Noise Reduction, Dynamic Noise Reduction, Edge Enhancer. Nothing about HDMI Input Mode.
I simply cannot find the HDMI Input Mode anywhere. And I am willing to bet JoeyFV will not be able to locate one either.
