Strato V black screen and audio cutout issues

[Gallo24]

Great question. I expect bugs on new product however my patience is wearing thin. Kscape is a high-end product, hence high expectations when something isn’t right. I have confidence they will improve this.

Watched BeetleJuice 2 on Friday and had 2 instances of audio-dropout when coming out of pause/intermission.

Watched 80 for Brady last night and had one instance...

As always, could not reproduce.

Both titles were HDR10 versions.

I do agree they are high end and no doubt have a great engineering team. I’m sure they will find the fix soon.

It seems like it’s going on for longer than I thought. Does anyone know are Kscape engineers looking at this?

Yes, work is being done on this right now. (Well, okay, not right now because it's Thanksgiving in Canada today, but you get the idea.) There are several different issues at play here -- some of them are purely in code we control; some are related to interoperation with other components. So, there are multiple fixes that need to be made, some of which involve engagement with other companies.

There will be fixes for some but not all of these issues in the next kOS release (10.20) this year. I expect that some of the interoperability issues will come later due to the need to involve others, but we should see meaningful improvement in 10.20.

Awesome thanks for the update Mike, I do understand it’s complicated for sure. Sounds good.

Thanks for the update. It is very frustrating and (somewhat embarrassing) when I have friends over for movie night to enjoy my expensive theater system and these dropouts happen. Looking forward to the fixes

It’s interesting because I have a NAS and Zidoo 1000 Pro which will have random audio drops too but on my previous cheaper system with only an AVR and older Z9S it never had any drops and they aren’t repeatable, it’s just random. As I’ve changed all but the Atmos speakers I have no idea if it’s a specific device or a certain combination.

I’ve not watched enough on the Strato V yet to see if it does it as well but it seems like the more devices you have the more chance there is for something to have a hiccup!

My chain is about as short/simple as it can get (at least with a projector) and I get the random blackouts rather often. Strato V -> AVR -> Projector.

I have two other devices...Apple TV and Zidoo Z30 -> AVR -> JVC both of which never show any blackouts or other issues.

I agree it seems pretty random since even when it does happen I have never been able to reproduce it given the same scene/timestamp.

GIven that its random and never reproducible it has to either be a handshake bug between the V and either the AVR/JVC or faulty/bad cable(s).

I have done my best to rule out cables. For the V->AVR I am using the supplied Pixelgen cable. For the AVR -> JVC I am using a Infinite Cables Active Cable

Mine was more simple like that with the addition of an HDFury as my previous Epson didn’t have HDMI 2.0 which I needed to get HDR on streaming.

Now have a Lumagen in play with one going to the JVC and one to the processor and every now and then it drops briefly. It could literally be anything though because Lumagen is new, processor is new, projector is new and I’m using a different HDMI cable to the projector.

I’m trying to think now if it mostly happens after I’ve paused the film or rewound but almost impossible to remember that!

Even more simple here. Strato V > LG G3. I've had audio cutout issues and more frequently lately than when I first got the V in July. Haven't had as many major dropouts on my HT setup which is Strato V > Marantz SR8015

 

[rafaelsmith]

So past week or so I have been encountering what seems to be a related problem....I can start a movie...exit...restart and audio is completely out/silent indefinitely ...only way to get audio back is to exit and restart again.

 

[Gallo24]

Anyone heard of a timeframe for the next KoS update? I thought we would have had one by. Ow to address some of the dropout issues.

 

[MikeKobb]

They are roughly quarterly, although of course if testing reveals any issues we will delay a release to address.

We expect the next release to be before the end of the year, with numerous improvements for Strato V.

Thank you Mike. Look forward to it.

Sorry if this is a silly question - when the new release is issued, will it be necessary to delete and re-download any films already stored on the Strato in order to get the benefit of the update?

I doubt it, but there is always a possibility.

kOS updates will not require you to delete and redownload any content in order to benefit from the improvements made to the operating system.

On the other hand, if our content team re-encodes a movie, then you would have to redownload that movie in order to see/hear the improvements.

I just got a Strato V and encountered something somewhat similar with a Denon x6700h with a 7.1.4. When using the supplied cable the screen would cut out very briefly every now and then display a Dolby Vision pop-up in the upper right. I switched to a new 6 ft monoprice 8k 2.1 and it doesn't cut out but still has the Dolby Vision pop-up in the upper right corner about every minute or two.
I ran the Strato directly to my Hisense L9H projector and have the eARC back to AVR. This got rid of the pop-up but the audio seems a bit lower.

The Dolby Vision pop-up is an issue with Plex also after some googling. I switched my Kaleidescape HDMI back to through the AVR and set my projector audio output to PCM and it fixed the pop-up issue. Not sure why since the audio is going from the Kaleidescape to the AVR but it works.
