I bought this converter https://www.amazon.de/gp/product/B01MXSK8YX/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 and another two actually. I Tried to connect Them with my jbl es 20 speakers which are connected to the amplifier. The tv is a Samsung ue65ks8080. And changed the settings audio format to pcm and HDMI audio format to pcm as well. And the speaker from tv speaker to audio out/optical. I can see the red light on the converter and on the optical port on the tv but nothing happens. No sound. when I connect any of these converters I bought on the gaming console, they work fine. Same cables and Same settings. Any idea what’s going on here?
