itjedi42 Posted November 27, 2016 Share Posted November 27, 2016 Have a Optiplex 990 I have have successfully got macOS Sierra running on. It has a Realtek ALC269 Audio chip on the board, and Im not sure how to get it working. You guys were amazingly helpful in getting my Touchpad and Audio working on my 6430, so I am posting in hopes that you guys will have a fix for this as well. Please let me know what information would be useful. I have attached my config.plist and captures of the Kexts in EFI and the 2 added to S/L/E Opti990.zip Link to comment Share on other sites More sharing options...
Trunyce Posted December 12, 2016 Share Posted December 12, 2016 What have you done so far which led you to no working sound? I have the 790 optiplex myself and it has the same codec as yours and i managed to get sound working by using AppleALC kext and editing the DSDT to have the correct layout. Although sound works, but only through the front headphone jack, the back speakers jack doesn't seem to output any sound through the speakers.
