[SOLVED] AppleHDA Audio stopped working since update to 10.13.6 - Optiplex 3020 MT with GTX 1050 TI

when I have audio over DP it seems to be random. If I achieve it from a cold boot then it is a gamble if I will have it again after either a restart or a complete shut down and boot.

 

I haven't booted into windows for a while so I can't comment on that

From my research of GTX 1050, you can only get DP Audio and not HDMI Audio, but according to your screenshot above, you're connected through HDMI. Also not all DP port will have audio, so will have to maybe remove and re plug or try different DP ports.

Can you post IOReg when DP Audio is working and when it's not working?
