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

Recommended Posts

are you connected through the HD4600 or GTX 1050 TI?

If GTX, did you update web driver for 10..13.6?

you can try enableing HPET clover acpi patch and reboot then retest.

but it sounds like you either have an injection/cache issue or HPET is gobbling up all the IRQ's

I don't know whats going on. I've just booted back up and its working fine. There must be a bug somewhere causing intermittent issues

 

Yep, definitely something intermittent. Rebooted and I've lost audio over DP again. I read somewhere that the HDEF and HDAU layout ID values need to be the same yet they are different for me. one is <03 00 00 00> and the other is <07 00 00 00>. Could this be an issue?

When you have no audio, is it after a reboot from Windows?

And when you have audio, is it after a cold boot?

 

Because my Haswell E6440 does that...
