I tried other tested I2S source (Lucien aka Lorien DiyAudio forum) to be sure is true I2S signal because B3 trought Sidecar plays perfect, using Teleporters USB-I2S>teleporter emitter>teleporter receiver>sidecar = no sound, pics of real I2S scope shoots:

1-Bitclock input Teleporter receiver, scope set 2V/cm 0,5us

2-Wordclock input Teleporter, scope set 2V/cm 10us

UserPostedImage

3-Data input Teleporter, scope set 50mV/cm 0,5us

UserPostedImage

As you can see aren't too different vs I2S CEC source so now I really suspect of Teleporters.

Please help.

Each Teleporter is hand tested by me. I feed 24-bit/96kHz I2S from a WM8804 module, then a Teleporter, through the test unit, then into an Opus DAC.

I am 100% confident that each Teleporter works.

What you want to check with the scope is compare each transmitter Teleporter channel input and the corresponding output from the receiving Teleporter. Do you see any differences?

I'm sorry Brian swaped WDCK - BCK between Lorien USB-I2S - Teleporter emitter, now sounds OK so I look for in other direction CEC I2S lines.
