Moderators Jake Lo Posted June 3, 2020 Moderators Share Posted June 3, 2020 Check for the following: Does the monitor have built in audio? Are you connected via DP / HDMI cable? Did you click on the Sound icon and switch it to HDMI / DP audio? Post IOReg file and state what connection is being use https://raw.githubusercontent.com/black-dragon74/OSX-Debug/master/IORegistryExplorer.zip Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted June 4, 2020 Moderators Share Posted June 4, 2020 Patch for HDMI already set in the Config file, not sure why it's not applying. According to the IOReg file, port 0x5 is still showing as DisplayPort. Are you booting with different sets of files than what is posted? For mic, try different audio layout-id. You currently have it set to 11 Try 3, 13, 17, 27 Link to comment Share on other sites More sharing options...
