ltooz_audis Posted May 23, 2021 Share Posted May 23, 2021 When I installed Catalina and Big Sur on my Dell 7352 Broadwell i7-5500u and HD5500, the ALC255 and HDMI sound didn't show up even with Lilu.kext, AppleALC.kext, Whatevergreen. I had to patch DSDT and add connector 1 to HDMI for it to work. This is how I did mine. Cheers, Louis Link to comment Share on other sites More sharing options...
