Hi,
I bought a LED controller like the one below. I've setup my brand new pi zero with hyperbian and got everything ready (hdmi switch -> hdmi splitter -> hdmi grabber -> pi zero -> chinese controller -> ws2812b ) but my problem is that the LEDs only light for half a second and then they stay off. They go red, green and blue once and that's it. The video grabber is working as I can see the live feed from the web configuration of hyperbian. From the very slim documentation that came with the chinese controller it would seem to indicate it runs adalight but that's my best guess.
I'd appreciate any help to troubleshoot this.
