Captured input - no signal - noise only

Hey guys,

I successfully installed Hyperbion, configured it and run it perfectly. I just noticed one interesting thing I am unable to debug or figure out. When I change anything in configuration and restart the Hyperbion, I see only typical "TV noise" which is captured - instead of original video. And for this noise, the LEDs are blinking, so the LEDs are working.

Does anybody experience similar problem? I needed to restart the RaspberryPi to fix the capture. It looks like the capture HW is unable to capture the source and put the noise as an input.

Thank you

Okay I will try to provide more details, please ask for more if you need it.

In general, it is not protected content - I have connected PS5 and there I played movies via Netflix, HBOMax, PS games etc - variable content grabbed via grabber. Everything is working as expected - my solution is:

1) Raspberry Pi Zero 2W

2) HDMI Video Capture with Loop - typical from AliExpress - https://www.aliexpress.com/item/1005002508144583.html

This works perfectly - configuration works, the LED lights are working and grabbing the video and lighting the LEDs as expected - in this case Hyperion is great and working but .. When I change anything on fly - during it is live, and then I save the changes and restart the Hyperion from the WebUI then after restart I got exactly what I described .. does not matter what source is there - laptop via HDMI whatver - the cables are new - no issues with cables, only after restart - the noise

Ah I see, this is the first setup I just found - also would like to improve it - may I ask you for some recommendation? I just found thread about the splitters, bot not grabbers Also would like to have more than 1 source connected.
