This might "sound" or read weird to you but I had to repair an Alienware 17 R4 laptop...of which was to give it a good cleaning. Now there was no hiccups while the laptop was put back together nor when I installed the latest version of Windows 10(20H2) and the necessary drivers, until a day later, the laptop suddenly decides to emit a static, crackle, pop, boom sound from the right side of the speakers without rhyme or reason. It'd pop as soon as you pressed the power button, it'd then emit the crash audio found back in the 90's on PC's with the crude audio output of that era.
After 2 days trying to narrow the problem(if the replacement battery was having a power delivery issue, or if the adapter I'd replaced was faulty or if I had damaged a cable or segment of the motherboard) and it came down to the silly Realtek drivers and the add-on sound amplification app that's bundled on the installer found off of Dell's support page. The solution was...hunt for Realtek drivers version 6.0.8816.1 and then manually uninstall all remnants of Realtek, reinstall the version listed above in an elevated command, reboot, then have OS perform an update to have the add-on come back...aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaand the horrible cacophony is now gone.
TL,DR; I hate it when Windows 10 and Realtek don't want to work with eachother in the driver's department.
