So this is a power state issue…
What happens if you disable C6 state in BIOS? (I'm suggesting this because TrueNAS Core, which is based on FreeBSD, requires disabling C6 to run properly on Ryzen. Maybe Darwin has the same underlying issue?)

yes it is normal also in others system without problems
In the past data hub and with a bad bootloader)was possible to interact with data hub and destroy a perfect working audio)
@CaseySJ if your system goes to sleep in a correct way
Sleep / wake I mean
could you test Realtek 2.0 audio before and after the sleep/wake process?
If it is possible without any AppleALC Alcu kext
thank you
Hey Casey,
Maybe you have this fixed already.
I'm sure you already tried but I had an audio issue on a 5950x - did you try disabling Global C-State Control and also make sure Eco mode is not enabled?

mario@marios-Mac-Pro ~ %here it works fine both via HDMI than Realtek USB 2.0 audio or any USB cheaper or not audio (without any kext)
@etorix
I’ve only tried Ubuntu (latest LTS release) and it works fine. No audio issues or PCIe issues.
Unfortunately setting FSBFrequency to that value does not improve audio playback.
This system does indeed sleep and wake properly. Just tested audio as follows:
- After waking up from sleep with AppleALCU enabled
- After waking up from sleep with AppleALCU disabled
On this board we have the ability to disable global C-states rather than a particular C-state. Alas, disabling global C-states does not improve audio.

If a simple little utility like SpeedKeeper can make such a significant improvement, it seems someone with kext experience would be able to develop a more technically sound solution. This seems to be a solvable problem...

The best part of running all these audio tests is having the pleasure of listening and re-listening and re-listening to Disturbed's cover of The Sound of Silence!

It seems that SpeedKeeper needs to take priority in the scheduler somehow to make the fix perfect. The audio was great when Mac idle (youtube on Chrome). When Cinebench runs the breaking gets worse, single thread cinebench has moderate distortion and multithread cinebench breaks audio even more.

Can you try 54000000?
Just tried it, but alas no luck. AmdTscSync.kext does load and run, but also fails to yield an improvement.
This was released last week in some regions including the U.S. My board was upgraded to 0705 last week.
Please see post below: "There's someone in the Discord server with a Gigabyte motherboard, even with disabled iGPU the internal audio is still garbage."

Is it possible to schedule the cores yet? I'm not a fan of these e cores as they seem to be quite a lot slower than 6700k cores. Last I heard Mac OS treats them the same which really isn't ideal imo. I can't tell you practically anything about the Intel 13xxx because they are under NDA... but...
