Thanks for sticking around, really helped me move forward with it. I had that idea too. I tried extracting the driver files from AMD GPU driver installer and installing them in Device Manager but it didn't do anything. And another I idea I had is to try to install them one by one but then I got...

Guys, I think I did it. An AMD Display driver caused DPC count of ntoskrnl.exe to go high, throttling cpu. I found this post on reddit and went to the second solution. What I did was: 1. Downloaded and extracted PowerSettingsExplorer.zip contents 2. Launched PowerSettingsExplorer.exe as admin...

Been playing around with Windows Performance Recorder + Windows Performance Analyzer. As far as I could decipher numerous reports I've made across the day I can half-confidently say that the audio lags are occuring during some background work that windows does while in screen off state. I've...

I guess running Windows Performance Recorder + Windows Performance Analyzer is an option now to go deeper to see what causes DPC to run high. Pretty sure it will be something amd related

Yeah, been there. Did that. Requestoverride didn't do anything that I noticed. I think legaacy kernel caller is a substitute for some drivers that are either deprecated or just not installed correctly. I also ran LatencyMon to see what causes DPC latency to be high and noted that there are two...

After OS boot Legacy Kernel Caller and Power Manager lines go away after some time while using the laptop.

feels like there's something with the driver that is either related to streaming audio or somehow related to power which doesn't do what it is supposed to. powercfg -requests supposed to show my bluetooth device driver and say that there is an audio stream going on

Will try. A friend came by with a jbl go 4 speaker which supposedly supports low energy bluetooth. The same behivor with lags. I guess at this point everything bluetooth related isn't relevant.

Yes. Then all of the lines say None. Chrome is playing video and I guess that there is supposed to be a bluetooth driver that plays audio. But there's none.

Another observation I made is that when I play music through a regular usb speaker I see the driver in powercfg -requests and it also says that an audio stream is in use while with bluetooth there's no driver shown at all as well as no sign of audio stream being played by a driver. Needless to...

Tested this today. Exported all of the online drivers into a file, disabled bluetooth and exported all online drivers again. No difference in files. Will try more. WIll report back.

Will do. In the meantime took my jbl go 3 to work. Legcay Kernel Caller turns out to be just a name for the bluetooth driver of this speaker. If I connect airpods there's a normal driver name. It doesn't influence how modern standby works. On the work laptop bluetooth works just fine with the...

Ran powercfg -requests. When playing music through bluetooth there's a strange driver under SYSTEM - Legacy Kernel Caller. It appears only when transfering data with bluetooth. I went as far as put the original wifi module chip into the laptop and it's the same. What is more interesting is that...

Found this in sleepstudy report. Some udentified driver seems to be causing troubles in S0. I don't have any unknown drivers in Device Manager so I am wondering how I could discover what is this driver.

Correction. I use an external usb hub to connect ethernet cable to the laptop. SInce I have only 2 thunderbolt ports, I plug the charger into the hub and charge from it. I removed it and plugged the charger directly into the thunderbolt. An hour passed, no stutters while external monitor...
