I recently bought a Samsung 55" 4K Ultra HD LED TV. I have an older model Technics SA-AX530 AV control stero receiver. Changed the TV itself from the TV speakers to Audio out/optical. The tuner is working fine so I know the speakers work, just having a hard time getting the audio to my stereo speakers instead of using the TV speakers. I just bought a Musou (HDMI to HDMI +Audio) and viewed the instructions and its not working. I have pictures but couldn't figure out how to upload. Any guidance would be appreciated. Specific instructions would help. Did I buy the correct converter? Thank you so much for your knowledge.
