Let's not rush things...take it nice and slow like...

I wonder if the PC has some sort of software that changes the audio format, and when you start video it switches it to PCM.

I would try:
Enable applications exclusive option in the sound card settings
Change output formats (16vs24bit; 44.1, 48, 96, 192khz)
Different PC

Hello all, I need your input for this weird behaviour.

System:
DMTX-4KZ-302C ---> DMPS-4K-350C -->? HDMI out to a Dolby CP-950 sound processor.
DMPS and enpoints are configured to pass untouched audio streams throughout.

On a windows PC, either through web browser or youtube or a playback with VLC, the sound starts around 5s after the video, it's not out of sync, it just "unmutes" 5 seconds later than the video.
If I press "pause" on the video for more than 10 seconds, same thing happens, the video starts moving, but no sound for around 5s, again, A and V are perfectly in sync after this mute period.
If I unpause the video for less than 10s, the sound starts right away along with the picture.

Does not matter if I use 5.1, 7.1 or stereo.

If I connect directly into an HDMI input on the DMPS it's the same problem.

If I connect the PC directly into the Dolby sound processor it's OK, sound starts at the same time.

If I use a MAC computer, the problem does not show, I can pause for as long as I want and the sound comes right away.

We tried an EDID emulator between the DMPS and the CP950 so Crestron sees something else (it was confirmed) and the problem remains.

I'm puzzled,? what happens in a PC when you start or pause a video for more than 10s?

Any insight appreciated.
Thanks for any input.

Edit---- We found a windows PC that didn't exhibit the problem, it's a Acer gamer PC with obviously a better sound card.

I would just find an old RMC3, which will run the prowl interface and EISC it to your CP2e program...way less of a science project...

Depending on the size of the program you could also just convert the program to run on the RMC3 and change your CP2e to be a slave for the ports...

Short of upgrading the processor, I have this crazy (but reliably working) idea of using an industrial-quality Raspberry Pi (such as the Iono Pi from Sfera Labs, $300) and using it to do work that's not in the specific Crestron processor's wheelhouse, and then use basic signaling (such as contact closure, TCP/UDP, or RS232) between the Crestron processor and the Raspberry Pi to trigger things.? I am using this solution to solve this exact problem and it's working well (except I'm using straight SMS rather than Pushover, just as preference...but could have gone either way).

I really wish there was a PAC4 to replace the PAC2.? Because of that, I totally understand the reluctance to call "upgrade" the cleanest solution to some of this 2-series equipment, especially where it's doing its job just fine.? That's part of why I invested my effort into trying out RPi's as an adjunct solution.

Out of the box, a Raspberry Pi will reliably boot to a desktop or shell prompt (your choice) in under 30 seconds, and run only whatever is configured to start on boot.? It doesn't boot up demanding your permission to install updates, login to your microsoft account, or try the latest subscription offering (like Windows), it won't even ask for a password (unless you configure it to)... it just fires up and does your thing 24/7.? No open network services unless you install some, so not updating the device is no big deal.? The default desktop install includes a basic Python IDE and debugger (Thonny) so it's immediately useful out of the box for scripting away some sort of task (just connect a monitor and keyboard, or enable built-in VNC and log in remotely).

By "your thing", in my wheelhouse that will be a Python script that simply listens for the Crestron trigger of my choice, and then takes the actions I choose.? I have developed a pretty robust Python script that uses an API provided by Twilio to provide some very rich text messaging triggered by Crestron processors, including the ability to have the user reply to the texts and ask the Crestron processor to do things (all using basic Serial I/O or TCP, they work equally well).

I've created S+ modules to send small or large numbers of Crestron serials (digital/analog/string) over a single RS232 or TCP connection where I want richness that's greater than a single digital.? Example, a Raspberry Pi responder that allows all controlled doors and fireplaces to be checked with a single text (the word "check") and it responds with which left on/open on the Crestron system.

The ability to do text messaging on a Crestron processor is, well, you get what you get here -- but easy to do and customize on a Raspberry Pi, especially where ChatGPT (which knows Python far better than S+) can provide quality help with Python when it's not your native programming language (it isn't mine).

The advantage with Python is the number of third party libraries out there (so talking to Twilio is as simple as installing Twilio's library... prowl and pushover are both supported by libraries) and the fact that Python is targeted toward beginners and people who just want to get things done, while being robust enough to be used in serious business.? ChatGPT can provide working examples of basic usage of all of these libraries and then you just take it from there.

Hello everyone,

One of my client have an old Crestron setup. Now he wants to receive push notifications on his mobile. Prowl & Pushover don't works with 2 series processors. Can anyone help me.

I have only noticed the overlay when using h264. I haven't had the same issue with MJPEG

I have found that some cameras (non-axis) will leave a video over-lay on screen when the iOS Crestron Go app is closed or put in the background.
This is despite using the same join for enable/disable video as the subpage.
This is an intermittent bug and not always reproducible. Never happens with Axis camera streams.

Using the Embedded Video Smart Graphic (version 2.19.00.99) control to show a RTSP stream from a camera. It works find on the TS770, but when I convert over to the Crestron App and bring it up on the iPad - the Video image is "floating" above all pages in the app? There is no issue with the video. I tried adding a subpage with the just the embedded video smart graphic. I was able to confirm that it is just the embedded video smart graphic image that is "floating" on top of everything, and it is transparent as I can access the button functions lying under the video graphic. I then rolled back the Smart Graphics back to 2.15.02.09 (2018) and still had the same results. The video smart graphics stream is even riding on top of the Crestron App when it is refreshing and does not change during the app refresh.?

I've found a new site to host my blog so for those that want to see even more content I've written about smart home technology you can find that using the link below. The process of exporting all my old content from Blogger and importing it into WordPress was far from perfect. So there are formatting issues with old posts and images that didn't import. I will see what I can do about correcting some of these issues over time.



Thanks

If you can get your hands on the Crestron Home Elements version 2 or above it should have it

Hi All,

One more file i'm hunting for in order to compile this project and complete it if anyone can help, TV Presets CRPC Interface v1.2.cmc

Thanks

https://www.dropbox.com/scl/fi/cg7trt47wqpdjjmn7ylvd/TV-Presets-File-Manager-v1.1.cmc?rlkey=mtddt6u0t3wpjdomgyqj9qhs7&dl=0

Does anyone happen to have module called TV Presets File Manager v1.1, I'm working on a system and i'm missing it in order to compile, hoping someone might have.

Thanks

There is the possibility of importing the wrong version of the .clz for the Biamp Tesira modules. The same .clz files me was used for 3.0 3.2 and 3.3,
but they are different files with different methods available.
Try importing demo program from Biamp for the 3.2 version of the modules, then go back and compile.

Got the same or similar answer. The radio service will not reactivated and there will be no?

alternativ service. The only way is to send the URL of the radiostation by serialstring to the?

PlayMatching$ serialinput of the ATC card.?

?

Did not have time to test it, but that was the info I got and for the customer I was asking for?

this could be a solution for now because selecting some presets would and listening to the?

radiostations would be OK for him. Maybe this can get hard if the stations change the URL

often, but we will see.

Looks like a clz is missing, or the Simpl+ files are expecting the clz to be somewhere they’re not.

You are using a 3 or 4 series processor, correct? I would delete the splwork subfolder and recompile. If you get the error again you may want to download the modules from Biamp as something may be corrupt or missing in the archive.
