flexrac Posted November 13, 2020 Share Posted November 13, 2020 Dell Optiplex 5070 9th gen Core I7 8gigs ram ALC255 with voodoo Big Sur Radeon WX 4100 low profile 4gb Opencore 0.6.3 I have some questions: I have Big Sur installed with Open core Sound is working with Voodoohda but only out of the back, if I plug headphones into the headphone jack, I can see something is connected but get no audio, not a big deal. I would like to get apple ALC working on this build but don't know what I'm doing wrong. previous dell with similar audio (ALC255) only gave me audio from the front, please help if you have any suggestions Also, although everything seems to be working and I am logged into my apple account I am seeing some strange things 1: my computer is registered as an Optiplex instead of A Mac , you can find this under your Apple ID 2: my serial number in about this Mac does not match that of my Plist, I think it's taking it from the dell bios, how can I fix this? Update: 11.14.2020, working OpenCore folder added, see below Sound from the rear out working with proper levels (Thanks Jake) Headphone jack in the front not working I have dual monitors working for the radeon graphics Never put my PC to sleep so sleep not tested No HDMI device connected so HDMI audio not tested Adobe photoshop and Lightroom working Final Cut launching but have not edited anything yet I need to find a good usb wifi adapter or a low profile internal setup Optiplex 5070 OC 0.6.3.zip Quote Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted November 13, 2020 Moderators Share Posted November 13, 2020 You have VoodooHDA enabled and AppleALC.kext disabled. Should be the other way around. You don't need VoodooPS2Controller + plugins for Desktop, those are only for laptops, you can remove them. Quote Link to comment Share on other sites More sharing options...
flexrac Posted November 14, 2020 Author Share Posted November 14, 2020 enabled it again and went through the ID's and still no sound, reverting to Voodoo but will keep researching it. Quote Link to comment Share on other sites More sharing options...
