Hi xilolee. Can I tack onto this and ask for assistance with a similar issue? I've been having these crackles and pops since March 2020, and HDAudBus.sys showed up for the first time in my LatencyMon report, leading me to this thread which seems to have a similar issue to mine. I want to see if I can sort this out as well. I have been trying to do so since that summer (I had to wait as I was finishing my final term of my second run at college, when the pandemic started, and was swamped with things to do at the time). Would like to PM regarding fixing this if possible but I can't start a PM unless I post some posts first.
An interesting quirk is that my PC has stopped being able to use the High Definition Audio Driver. It doesn't work at all, so I am forced to use Realtek to get any audio. This started with the update to, I think, build 2010 (1903 is where the crackles and pops started). Until then I could use either driver. I wonder if there might be something related to this with my PC, too. I really don't want to have further updates in version until this is sorted out as I suspect a registry entry to deal with a driver might be the necessary fix.
