Hello. I have such a minor problem. I have a TV at home (Samsung) and an older DVD player (Panasonic). When I turn on the TV and turn on the player, the sound goes to the speakers near the player. However, if I connect a USB flash drive to the TV and play a movie from it, the sound only goes to the TV. The TV does NOT have an analog audio output, the only audio output is optical - "Audio Optical OUT" I have a SCAR cable connected. What can I do to get the sound when playing USB movies on the TV to the speakers at the player? I thought of buying an amplifier with an optical input + optical cable and connecting a new speaker, ideally wireless. If necessary, connect with existing speakers, unfortunately they do not have a classic CINCH, but the contacts are closed (+ -). Another option would be this https://www.mironet.cz/prevodnik-z-digitalniho-signalu-spdif-a-optickeho-toslink-na-2x-cinch+dp162316/ but won't I lose the 5.1 sound? In conclusion, I want to say 5.1 sound, not just stereo sound. Thank you for the advice.
