Issues with Catalina after upgrade from Mojave

I first had Mojave on my Acer Aspire V3-772G installed and everything worked on that machine (except for WiFi ofc) Then I wanted to install Catalina next to Mojave. At first the installer didn’t boot at all. I found a solution on the internet to simply add the file “SSDT-EC.aml” to EFI/CLOVER/ACPI/patched. However I was no longer able to use USB then. It said “USB accessories need power” So I looked this issue up and found out that I simply had to delete “USBInjectAll.kext” But now my audio no longer works! It doesn’t even show up in system preferences Does anyone have a solution for that? I guess I have the Realtek ALC282 codec
