BMW Logic 7 Audio Cutting out, SOS Warning Light HD

I had for weeks issues with my Logic 7 sound system cutting out every minute. After researching it on the web, I found out that the Logic 7 uses optical audio cables to run the whole system. I used an optical loop to rule out the defective module. You can find this loop here: https://www.amazon.com/Optical-Connector-Diagnostic-Navigation-Mercedes/dp/B06XFFTB5V/ref=sr_1_3?ie=UTF8&qid=1509942010&sr=8-3&keywords=optical+loop
