Convert Coax Digital to Analog

I have this TV:https://www.lg.com/us/tvs/lg-32LF500B-led-tv
I have this amplifier: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

My inputs to the TV are antenna and a Roku stick. The TV has a coaxial audio output jack. I want to be able to convert the coax audio to analog so I can use the AUX input on the amplifier to listen to broadcast TV and the Roku device. I have tried to accomplish this using a device such as this:
https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

This does not work. I know the TV output is OK, and I know the coax audio I'm using are good because I can connect them to a different amp, one with a coax input, and I get audio out from the amp.

Please advise- thanks for your help.

After trying several devices, I finally recognized that the problem was that the TV audio was dolby 7.1. Once I found an adapter (STELLAR AV ST-DAC-71) that was able to process that audio format, I was able to route the audio from the TV to the amplifier via the TV digital audio output jack. This did not however result in any improvement in audio quality or audio level.

Make sure your TV is outputting PCM and you Roku.
