Review on Enhanced Connectivity: ROOFULL Toslink Optical Coaxial Converter by Badpuppy Warton

I have a wall mounted TV above the fireplace and the HDMI cable runs from behind the wall to a receiver in my basement (35ft). I used to rely on HDMI ARC to send audio from the TV to the receiver and speakers. ARC is unreliable and very inconsistent in delivering audio to the speakers when playing some videos straight from the TV. To solve this problem, I planned to transfer the sound from the TV's optical output to the receiver's optical input via a coaxial cable installed for cable purposes. To convert the optical output signal to coaxial, I bought a ROOFULL DAC and used another converter on the other end to convert the coaxial signal to optical. At first I was a bit confused about how to use these converters, but after contacting support I was able to resolve related issues and they ended up working like clockwork. Customer support was very responsive. This is my TV setup end --> Optical output --> DAC (optical input) --> switch position to SPDIF -- DAC (coax output) --> Coax cable, receiver side --> DAC (coax input) - - > Switch position to coaxial -> DAC (optical output) -> Receiver (optical input). If you don't understand how the switch works, you only turn on this device optically to tell the converter that the signal type is the input signal. If the input signal is optical then the switch position is toward SPDIF, and if the input signal is coaxial then the switch position is toward coaxial. Hope this helps anyone having trouble with ARC. By the way, my TV model is Samsung NU8000.
