Hi,
After two weeks of trying to install Catalina on my HP ENVY 34 AIO desktop, I finally got Catalina up and running thanks to your config.plist. There are two issues I have right now. 1. There's no sound (ALC293). 2. When booting with the second monitor plugged in, I get black screen on the main monitor and video on the second. In order for dual monitor to work properly, it has to boot with a single monitor then hot plugging the second one. Any help would be appreciated.
