This solution worked for me! For me, one was set to 05 00 00 00, another was set to 04 00 00 00, and the final was set to 00 00 00 00 already. I changed them to all be 00 00 00 00 and it fixed the problem! I did need to restart my computer and I found some duplicate keys in the "upgrade" path that I also changed before that restart.
Thanks again, this was incredibly helpful -- my headphones did not make a pleasant sound after being silent for a few seconds!
I don't know if it would help, but I looked for HKEY_CURRENT_USER\Software\Realtek\RAVCpl64\PowerMgnt in my registry and it is not there (Realtek is, but not RAVCpl64). Any ideas as to where else the audio power settings might be? I also went to try replacing the Realtek driver with the Windows audio driver (which I'm pretty sure I've already done in one of my other attempts to fix this problem over the past 3 years), but the only audio driver Windows finds on my C: drive is the Realtek driver.
I've been living with this problem since I bought my Dell laptop three years ago. I look for a solution, spend a few hours on it, then give up for a year. I can live with it, but what drives me crazy is when I forget to unplug my speakers from the audio output jack after listening to music, settle in for a nap, and am awakened by a large CRACKLE. That sucks!
I've found that usually I can fix this issue by either PowerMgnt patch (actual key you're looking for is HKEY_CURRENT_USER\Software\Realtek\Audio\RtkNGUI64\PowerMgnt) or the PerformanceIdleTime patch, which is located at "\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class". Right click the "Class" key and then select "Find..." and search for PerformanceIdleTime. Most likely you'll find it in a RealTek sub folder, but make sure it's the RealTek and not anything else like Intel Audio. Change this value to "00 00 00 00", all zeros.
Look above your post for more info on this 2nd fix, as it's nothing I've created myself, but seems to work if the PowerMgnt doesn't.
My pops and noise came with a new GigaByte Z690 UD DDR4 mobo installed two weeks ago

Did not find currentUser\Software\Realtec etc.
Where search found "PerformanceIdleTime", its value was already 00 00 00 00
Hmm, so there must a 3rd fix for newer boards that no one knows about yet. My wife just bought a $1,800 HP Spectre laptop with Windows 11. The OS audio delays in playing about 1 second. I tried to see if these 2 fixes would repair it, but they didn't. Doesn't bother her, so it's not a priority for me to see what's going on with that one.
So if you haven't yet, install the Realtek audio driver from Gigabyte's website for your board. Maybe the driver will fix it, or you'll have some registry keys to alter afterwards. Plus make sure the PerformanceIdleTime key you found belongs to Realtek, and not an HDMI audio out from Intel etc.

Thanks for the recommendation. I did download those realtek drivers from GigaByte 4 days ago but they made no difference. This looks like a bottomless hole.
Would installing a separate sound card make any difference?
I would assume so. I can't say I'm 100% sure because I don't know the cause of your problem. But as you can see here many people have issues with Realtek chips either popping for delaying. Just find a card with a different chipset. Maybe SoundBlaster or something, then you could even gain some hardware accelerated audio effects, reverb, echo etc.
Also make sure your speakers are plugged into the correct jack in the back. Usually the green one, which is line out, it'll be the middle one. Try to adjust your volume levels too. Try setting low in the computer level, then adjust your speaker volume knob to a suitable level. Sometimes you'll hear cracking if your computer is set too high to the speaker.
Bumping this to say that I tried EVERYTHING in this thread but nothing worked.
I reinstalled Windows 10 numerous times hoping that something within the install would fix this, and sure enough, it did on the 5th install.
So if none of the suggestions above work for you, then your laptop is a special case like mine. I would recommend doing a clean install until the popping is no longer.
Didn't expect to see this. I'm old so my memories of having explained my fix and of thanking those who helped may not be real or may have been in another forum.
I reduced the sampling rate and the noise disappeared, rikki-tik. That's it.
