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

[PaintArm]

Yes, just booted into it. Still no audio over DP/HDMI. hmmmm

[Jake Lo]

are you connected through the HD4600 or GTX 1050 TI?

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

post new debug file

[PaintArm]

I'm using the DP on the GTX 1050 Ti. I could upload my config.plist for you if that would be any help? Web driver is updated yes.

ok so I changed the audio inject value to 2 and now I have audio. Thanks for the help with the DSDT @Jake Lo. Much appreciated

[PaintArm]

So this morning I booted up and have lost audio again. Nothing has changed and it was fine all day yesterday

[Jake Lo]

can you post screenshot of Status and PCI List with DPCIManager?

[PaintArm]

I can't as its being quarantined as malware. Sorry

[Bronxteck]

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

[PaintArm]

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...
