No Audio with Co-Star and New Marantz AV10 Processor

[jt_M3]

Hello. I am reaching out to the community hoping someone might be able to replicate or has a fix for the problem I am experiencing. I recently upgraded my system to include a Kscape Encore server and Strato C player as well as the new Marantz AV10 processor. Since I also have a Kscape Premier system, I also added a Co-Star to "pair" the two systems. The issue is as follows:

I can see my complete movie catalog on the "paired" interface. I can play any UHD or HDR contact on my Strato with no problem. However, when I play any title from my Premiere system such as a DVD or Blu-ray, I only see video. The audio is missing. This is confirmed by the AV10 which reports it as unknown. It doesn't matter which title I play, the audio problem persists. If I stop the video, and then select a UHD or HDR title from the Strato unit, it plays as expected. Again the issue is with the audio playback on from the Premier hardware only. At the moment, it is paired to my M500.

I believe I have isolated the issue with the Co-star and Marantz AV10 combination.

Trouble shooting thus far:

• I have both a fully functional M500 and M300 player. I have paired both with the Strato and Costar, and the exact same issue is experienced.
• In the M500 Audio settings, it is set to Bitstream pass-through. I also tried setting it to player decode, and the issue is still present.
• If I swap the HDMI inputs on the Co-star between the Strato C and M500, the problem follows the M500.
• All HDMI cables are the same length and type/model and were just purchased new. I also tried older cables, and issue still persists.
• If I bypass the Co-Star completely and plug the M500 or M300 it into a HDMI port on the AV10, it works perfectly. Even with Bitstream Pass-Through selected.
• The Marantz AV10 has the latest firmware installed.
• Kscape support advised to try my old processor which was a Marantz AV8003. Since it is no longer installed in my rack, I did take the Costar HDMI output and feed it to the AV8003. Without any amplifiers installed on the AV8003, I was able to confirm the audio was being decoded from both the Premiere and Encore system via Costar.

Any help would be truly appreciated!

Just to confirm, do you have both downloaded & imported content on the Premiere and tested playback with each?

 

[jt_M3]

Yes I do. I have both physical Blu-ray discs in my vault, which are imported as well as Kscape store downloads. To reiterate, if I bypass the Co-Star and plug the M500 player to a dedicated HDMI port on the AV10, it works as expected.

 

[Transepoch]

Sure, but the Terra is all downloaded content, so I just wondered if both downloaded & imported content acted the same on the other side, in case it was a weird signaling hiccup between the two types.

 

[jt_M3]

I appreciate your input and help. But yes, whether I play an imported movie or downloaded movie on the “Premiere” side, I have no audio.

Seems like the Kramer switch (which has a bit of edid management) and the Marantz AV10 are not liking each other for your Premier component. Anyway to change the characteristics of the HDMI input on the AV10? Also, maybe try a different HDMI cable from the Premier To the Kramer costar switch.

I have the same problem with a McIntosh surround processor. It appears to be an HDMI handshaking problem. I am waiting for a Key Digital device that hopefully will clean up the handshaking problem (installed between the K-scape and the surround processor).

I contacted Marantz support and they walked me through changing some of the HDMI configs. However, none of them were successful. And yes, I tried various HDMI cables with no luck.

Which McIntosh processor are you using? Also, what is the Key Digital device you are referring to exactly? Is this from a recommendation or do you perhaps know someone that has it and fixed their similar issue?

McIntosh MX160, Key digital KD-FIX418A-2, recommended by the installer "give it a try but it doesn't always work" (and it's currently out of stock)

Here’s another device which might help:

https://www.amazon.com/HDfury-DrHDMI4K-18Gbps-600MHz-Manager/dp/B07VK2WSWN?ref_=ast_sto_dp

Ive used it before. You could return if it doesn’t work. I am thinking of replacing my 8805 with an AV10.. Maybe I will wait!

Thank you @SJHT !
The HD Fury your recommended solved my issue. It is a bit quirky to work with, but it worked. Thank you so much for your input. It is truly appreciated!

In case you did not see my reply, I just purchased this unit off of Amazon recommended by member SJHT. And it worked! Worth a try and they are in-stock. Good luck!

if you purchase direct, they charge a lot for shipping and I highly doubt any return process is going to be as simple as Amazons….

Hello jt_M3 could you walk through the steps you did after you purchased the device? Im in the same situation, no audio for me as well - so im thinking of getting going this same device. In the DrHDMI device, what channel do you select?

 

[SJHT]

K needs to figure out what is going on with this setup. Seems like the Kramer switch used in costar might be getting a bit dated for newer AV processors. Good news that using the Dr HDMI is good interim solution. SJ

Hello. Yes, the DrHDMI device did solve the issue, but I did not keep it for long. I was having issues with it when switching between HDMI inputs on my prepro. Instead, I found a similar device on Amazon which is actually cheaper in cost, and installation of it was a breeze. This one works like a charm and I am still using in my setup: https://www.amazon.com/gp/product/B09NPWKQYC/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

Ah thank you - will try the HDMI EDID Emulator Manager. Was it a straight forward plug and play - Any particular settings was needed? As I see there is something called an EDID switch. Do I need to set something with that? Im sorry im not very proficient on these technical matters

Did you use this device for any other source input like Apple TV? There seems to be a lag in the feed whenever I play a movie but it's only for a couple of seconds and I can live with it. I just thought to ask since you have the same AV10. Thank you so much for your help in this.

I just looked at the device, and I have all three DIP switch settings to "ON." I had no issue with any other devices so I only use this with my Costar and M500.

Sorry, forgot to add that this was the only thing I added and it remedied my issue with no audio playback on content from my Kscape Premier system.
