So I have the ROG STRIX Z690-A GAMING WIFI D4
My CPU is a 12700k.
I initially had Win10, it ran ok, no BSOD, and I don't remember crackling audio.
I upgraded to Win11 due to the fact that the cpu scheduler handles the 1700 socket ie 12000 series cpu's better, I had a number of games under Win10 that would peak out only a few cores and leave other unused. I "blamed" the games.
Switching though to Win11 the core / thread balancing is much better, those same games that used to max out certain cores were now more evenly spread and using more cores, great, I thought.
Then I started getting BSOD's: "DRIVER_POWER_STATE_FAILURE"
I did a bit of research, did the usual driver updating etc, the issue persists.
It usually happens right after booting, within 10min, if I can get past the first 10 or 15min then the system is fine.
I used WinDbg and here is the result:
https://pastebin.com/c6FpQKnCSeems to indicate an issue with audio referring to HDAudBus.sys.
Apart from updating all drivers I also ran SFC /scannow from a privileged cmd prompt, nothing wrong was found.
I am also running in max power mode and I have tried turning off everywhere where it allows the system to suspend or turn off devices.
The issues still stands.
The other issue is crackling audio when using the line out on the back, according to all the results I find I am not alone.
I tried to follow the steps in this thread:
https://www.reddit.com/r/ASUS/comments/sf4tau/fixes_for_realtek_alc4080_sound_problems_on_asus/My issue is that the firmware updater "USB Audio FW Update Tool_VID0B05(2021-11-25)_ASUS.exe" does not find my usb audio, even though obviously I have it as it is on and working (apart from the crackling every now and then).
I downloaded that from the support page of my motherboard on the asus site.
It shows the following when run, even in admin mode.

The tool I was using is listed as:
Version -
2021/12/09 3.37 MBytes
ALC4080/ALC4082 audio FW update tool release
Fixed Line Out playing music is noisy
I did perform the following FW update as well:
Version 008
2022/02/25 2.96 MBytes
PD FW update tool
Whether it was successful or not I do not know, it just opened a cmd prompt, flashed a few things then disappeared.
I am running BIOS 1504.
While on the topic of BIOS, I see that some of the prior BIOS changelogs indicate things like...
Update USB PD FW to 1.0F.
Update Intel Microcode
Update Intel ME version 16.0.15.1735
...but 1504 does not, does that mean I jumped over and missed all those intermediary updates? As far as I know the latest BIOS should include all the updates of the prior ones or not?
I'd appreciate some help. All the initial WHEA 17 issues and then BSOD's and Sound crackling has left me a quite bitter with this board and it's far too late to return it, I also spent a lot on this upgrade and will have to keep it a good number of years as I can't afford to just swap it out for something else.
