Splitter Audio problems, Home Assistant Integration and RPi Zero 2 W GPIO

[luppercut]

Thanks for supporting this project. It's a lot of fun to tinker with.

For the most part I have it running with a few problems. I would appreciate any guidance on these points:

My EZCOO HDMI splitter causes audio drop out. I have higher quality cables hipping in to test that.
I've seen it mentioned that Home Assistant lights can be added, which would be awesome but I can't figure out hot to do that. Perhaps I need to upgrade to a beta version?
Currently I run HyperHDR on a Pi that's on the same TV as an SK6812 strip connected to an ESP that it's wirelessly connected to. In a previous iteration(older version of HyperHDR I think), I was able to control the strip directly from the Pi IO, but now I can't get that to work.

Hi
I dont now what splitter model you have but maybe it is damaged or edid is set incorrectly? I cant help with Home Assistant because I don't use it and the integration with HA is an external project - maybe some other user could help here?
Need full logs taken 2-3 minutes after start to see what's going on with the LED driver. Try to play an effect then.

Thanks for the reply!

I'm mainly unsure how to set it up with version 20. I chose GPIO piblaster and tried to set it to pin 4, which is what I think the data wire is connected to.
