No, not info.plist. Looking at your Clover folder, you'll need to change it in DSDT.aml and in Config.plist
No, just install AppleHDA_ALC283.kext (dummyHDA) to /L/E, you must have vanilla (untouched) AppleHDA.kext in /S/L/E
Remove AppleALC in Clover kexts or /L/E if you have it there too.
Since your DSDT and Config is already at layout - id 3, better to test this one first.
