Hello! I have an androidtv (noblex DM43x7100) and a micro theater Phillips mcd122. I bought a digital to analog converter and connected a optical cable from the tv to the converter and two RCA cables L/R from the converter to AUX IN in the micro theater. The tv has very few configuration to audio but I chose (external audio) and digital audio to PCM but nothing happens, audio goes through the tv in Netflix, YouTube, Spotify and cable. What should I try?? Thanks.
