Looking for an HDMI Audio Extractor/Converter to Analog audio as I need to send the audio back to the DA system (Crestron AAE/AMS analog input). The customer only has an IPTV box for source (Rogers Ignite TV, similar to Xfinity X1). Not sure of the TV brand so don't know what audio outputs it has.

I have found the Crestron unit (HD-DA-2 [Link: crestron.com]) but it is only capable of 1080P.

Also found the Atlona unit (AT-HDR-M2C [Link: atlona.com]), it is 4K but seems overkill with the web interface and is more than double the price of the Crestron unit.

Can someone recommend a unit they have worked with and has had solid success with?

Well, I would recommend this:
[Link: metrahometheater.com]

It is a 4 in 1 out switch (yes I know that you do not need the switch part) with full multi channel break out on the Optical and Digital Coax and well as a 2 channel mix down for the Analog Stereo port (3.5 mm).
But wait, that is not all.
It also has built in selectable (on/off) ARC out on the Digital ports.
And it does all of this at a very reasonable price.

I'd go instantly with the Metra piece if
*When it loses power, it returns to the input it was on when power was lost.
*The same goes for other details: resolution etc
*There's no stupid brilliant blue light that has to be covered for the room to be dark.
*The same goes for red lights.
*The connections are all on one side... no five connections on one side, one on the other.

Also, of course, if it performed as needed.

Ernie,
Are you saying that you have used the piece that Brent has suggested and experienced what you listed above, or you have not used this unit and are wanting to ensure your listed above items are met before installing into a system?

I've used this piece with 4k AppleTV's with great results.

Sorry, but I can't see how to answer this in a constructive way without referring to grammar.

"I'd" is short for "I would." "Would" and "if" mean that some condition(s) has/have to be met for something to happen. Inherent in that phrasing is that I have not used it, or that I've used it and it didn't meet these criteria. If I had tried it and it did not meet those criteria, I'd be saying "I'd use it if they fixed these problems."

I would use the Metra piece as well. Alternatively there is a Vanco 280573 with multi channel down mixing that has worked for me.

Brent, I just put the CS-HDMAB02 in a project and have lost audio a few times.  Rebooting the Metra piece brought it back.

Source was an Apple TV4k to an Epson 6040UB.  Using optical from the HDMAB02 to an audio matrix.  When the audio was lost there was no red light in the optical until it was rebooted.

Thoughts?  Haven't had time to call yet.

Here's how:

A "I have used it."
-or-
B "I have not used it."

These are partial answers, but not the entire answer to either half of SWOI's question.

The answer is no, no, or yes, and yes.
No, I have not used the piece, and (therefore of course) no, I have not experienced what I listed above, or yes, I have not used this unit and yes, I am wanting to ensure my above listed items are met before installing in a system.

Actually, I have answered more than was asked, as the OR calls for only answering one half or the other.

Let's tune back to our regular reality now.

Back to reality:

Why do you ask?

Lotsa nonsense above.

We have 50+ of these in service with 1 - 2 failures. Failures could have been attributed to cable used.

Well, that looks familiar: [Link: vanco1.com]

You folks realize the Vanco/Tripp lite is NOT 18Ghz right?

That sounds like the AppleTV has dropped the EDID stream, that can happen when it goes to sleep. When you reboot the ABO it forces the ATV to reset. We have seen same with many brands of extenders connected to the Apple TV.

Best (cheap) solution is put a timer outlet on the power supply of the ABO and turn it off every night between 3 and 4 AM.

Maybe but I always set my ATV's to "never" sleep (of course, that doesn't mean they don't).  The audio dropouts I was experiencing were all in the first day of install and happened a few times of testing withing 10-15 minutes.  However, audio has been working now for over a week.

All the equipment is already on controlled outlets (the ATV reboots weekly of course) so if the issues pop up again, I can add nightly reboots to test without a site visit.

Could the 4 input device you linked earlier have the same issues with ATV?

Thank you sir.
