Default Re: How to go from Apple TV digital out to MTRX?

This doesn't work because the extractor doesn't have a Optical IN for clocking. The result is the audio plays but drops out every few seconds.

No HDMI audio extractor I've found have an Optical IN, only OUTPUT.

Is there a better way to do this? I need all my MTRX analog inputs otherwise I just use them.
If your HDMI extractor also has SPDIF output, try the bellow AES/EBU impedance converter from Neutrik, connect then straight to the MTRX AES in and ditch the Hosa. MTRX needs to be at the same sample rate as the audio coming from the Apple TV out:
