So, I have on older install of Raspbian on my Pi 3B that I decided to upgrade. (Well, replace is a better word.) It’s been driving my Unicorn Hat forever and has had zero issues. But my new install of Stretch can’t seem to get the Unicorn Hat to work at all. Some of the examples will light up a couple pixels in the corner, but that’s it. If I go back to my old install, works like a charm all over again. (So, I know the Unicorn Hat is fine.)
I’ve tried everything I can think of to ensure that audio is going out over HDMI and not the 3.5 jack. (And it is going out over HDMI, sound plays just fine.)
Am I stuck without my Unicorn Hat when using Stretch? Or is there some configuration issue I’m not ware of? Thanks for any help you can offer!
