Realtek hd "popping" on outputs everytime a sound is made

I had the same problem. The only way I could stop this (stupid) behavior was to edit the registry. Look for the key "PowerMngt" and the key "Enabled". This should be 0. If it is 1 then you have the popping sound!

Here is the key in the registry: "Computer\HKEY_CURRENT_USER\Software\Realtek\Audio\RtkNGUI64\PowerMgnt".

Note! Every time you update the driver this value will default to 1. So annoying. Put this key to your favorites so you find it quickly the next time.
Caveat: I don't know if this will work on your sound card.

If someone still facing the popping sound problem, try the new setting below.
I have been testing this settings for month, the popping never come back again.

DelayTime 0
Enabled 1
OnlyBattery 1?

For me set Enabled to 0, you will get popping sound back soon or later.
I did not test other combinations, but this one works fine for me.

Try updating Realtek to "Microsoft HD Audio driver 19-10-2023" (forced) and then for test disable all Enhancements for the speakers
I had popping using "Loudness equalization" enhancement

Also did this that helped:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile\Tasks\Audio
"BackgroundPriority"=dword:00000006

Cheers

Thank you old shadow of the internet, it worked perfectly on my dell g7 laptop!

I bought a new Dell laptop in March 2020 and have had this same problem since DAY ONE. Every time a sound played, it would POP and every time a sound stopped, it would POP. It's been annoying for 6 months and I finally decided to search for a solution.

This worked for me. I found this solution in the Dell Forums.

I modified the power management settings for the 'RealTek Audio' via Windows registry (regedit.exe). Its a good idea to record or backup the default values before making changes below.

a) Navigate to the class path for Audio settings (this is the parent path)

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e96c-e325-11ce-bfc1-08002be10318}

b) Locate the specific class registry key for 'RealTek Audio' > In my case it was this 0002 (you can verify this by the 'DriverDesc' value = Realtek Audio)

Path should now be = Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e96c-e325-11ce-bfc1-08002be10318}\0002 (or whatever your class 00## is)

c) Drill down into PowerSettings key and modify the following values:

Current Path = HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e96c-e325-11ce-bfc1-08002be10318}\0002\PowerSettings

IdlePowerState = ff ff ff ff

PerformanceIdleTime = ff ff ff ff

5) Reboot your PC and the issue should resolved.
