Are you speaking about coil whine? I have not heard anything from my Vega other than fan noise.

Yea. I don't have coil whine issue in Windows but only in Mojave.

 

[pastrychef]

Yea. I don't have coil whine issue in Windows but only in Mojave.

I don't know what can cause coil whine or any effective fixes.

Does it wake properly with just one monitor?

No. Sometimes it does refuses to go to sleep even! It makes black screen but the machine doesn't stop. In that case normally pressing ENTER monitor will wake up properly. In other cases it does go to sleep but when it wakes up it will make black screen. No matter how many screens are connected. All in DP ports.

Check your crash logs for any mention of HDCP.

When others have experienced this, sometimes different cables helped.

Solved it... THE MOUSE WENT BAD! Wired mice never go bad on me. Especially a logitech wired mouse. Explains why it was working right, then quit. I stuck it on my work PC using windows 10, same funky behavior.

Ah. That's a different problem than if it doesn't wake...

Please enter the following in Terminal and post the output:

log show --style syslog | fgrep "Wake reason"

Also, this:

pmset -g assertions

I have this kind of stuff:

Do you have your SSDT for USB set up? Does it sleep if you disconnect your ethernet cable?

Sure... here it is! Regarding the ethernet cable... let me try.. I will disconnect and then back online and report...

I don't know what can cause coil whine or any effective fixes.

No worries. Another issue for Vega 56:

I have changed the RGB pattern of card in windows. But it can't stay my setting after macOS wakes from sleep.
