How to go from Apple TV digital out to MTRX?
I want to extract digital audio from an Apple TV 4th Gen with a HDMI + HDMI Audio extractor box. This extracts an Optical output from the HDMI signal. This then goes to a HOSA Optical to AES/EBU converter box. And from here it goes to the Avid MTRX AES-in.
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.

Re: How to go from Apple TV digital out to MTRX?
So you are trying to record the audio signal?
Usually the output from the Apple TV is a Dolby encoded output. Are you tying to record a simple stereo, 5.1, or Atmos?

If clocking is the only issue change you Pro Tools/MTRX setup to clock from its AES/EBU input.

Thanks, I just tried that but get a SYNC Loss alert and the audio still drops out every 5 seconds or thereabouts...

Re: How to go from Apple TV digital out to MTRX?
Then you likely have other problems in the conversion chain than just clocking. Can you try swapping components/cables. Can you run TOSLINK into the AES/EBU converter say from a CD player or a Mac with optical out to test that works. Is it an old Apple TV with TOSLINK out that you can go directly into the TOSLINK Adapter?

Re: How to go from Apple TV digital out to MTRX?
Any chance you have a Dante card on your MTRX? I use these adapters to get as much audio input as I need....
https://www.amazon.com/Audinate-Dant...C4Y?th=1&psc=1 I know it doesn’t directly solve your problem, but thought I would mention that Incase the sync issue doesn’t work out.

Re: How to go from Apple TV digital out to MTRX?
Thanks for that, looks interesting. I'd get a Dante card if it's solve this clocking issue, since I'd to stay digital if possible. But you're saying with this I could go analog into the Dante card. That might be the way to go...

Re: How to go from Apple TV digital out to MTRX?
Not sure going Dante to just get analog would make sense.
Do you have something like an RME ADI-192 DD you can borrow? That gets you SRC (pretty sure it regens off the input clock at the same sample rate) tied to a clock signal. Super handy boxes, but overkill in general for this... but if you can borrow one. Are other MTRX as touchy for locking to AES/EBU? I'm more guessing your Apple TV may be running a little loose. But if it happens with other stuff... What computer do you have? Does it have optical in? (I'm guessing from your info you mean a late 2013 trashcan, so no). Maybe consider buying a USB or thunderbolt interface with optical in and switch to Pro Tools Standard while importing that S/PDIF input. |

Re: How to go from Apple TV digital out to MTRX?
All my old Pro Tools systems from years ago when I had outboard Lexicon boxes, etc., were all word clock synced. Never had any problems. But stuff without word clock needs both AES in and out connected. Then it works fine. The Apple has no IN. Apple TV is consumer-grade stuff unfortunately.
My computer is a trash can Mac Pro, no Optical in... The RME box looks good...thx.
