This is a huge issue for me as a music producer using FL Studio, and happens quite often, both on stock Dell Realtek drivers, and KSMRD stable / experimental.
EDIT: Probably fixed by changing powersettings again like we were doing originally in v1 of KSMRD?
For me, the new location for powersettings (ConservationIdleTime, etc) is at Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class{4d36e96c-e325-11ce-bfc1-08002be10318}\0018\PowerSettings but it may be in a slightly different location for others.
If you're on KSMRD experimental branch you can find the subfolder that contains the relevant powersettings by searching for "KSMRD Audio" in the registry. If this doesn't resolve the random noise issue, perhaps setting all other audio related powersettings under Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class{4d36e96c-e325-11ce-bfc1-08002be10318}\ will fix it.
This is just some theories and a place for me to note it down, I need to test it.
Currently testing just Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class{4d36e96c-e325-11ce-bfc1-08002be10318}\0018\PowerSettings keys set to FF FF FF FF
