Couldn’t edit my original post so I thought it best to create a new one with all the updated information.
Sound distortions since early/mid December, immediately following large Microsoft update, approximately 12/16/2017.
Popping, crackling, high pitched stutter like sounds during operation and on boot after the HP logo shows up. System does not appear to make sounds when unplugged from AC Adapter. Worsens when multiple browser windows are active. Also makes sounds from laptop speakers when sound is muted or headphones are plugged in.
Purchased new AC Adapter, installed and ran the latest versions of both BIOS based and Windows based HP Diagnostic Utilities, no errors found. Battery check shows no faults. Battery was exchanged under the recall.

All drivers appeal up to date per HP Support website, HPSA and Intel.
Searching the HP Support Forum I am seeing this problem across multiple HP laptop hardware platforms using different onboard audio devices. The majority of the problems seem to have appeared immediately after the latest large Microsoft update that rolled out fall 2017. I have tried multiple variations of the fixes suggested but have not found any solutions. It has been over a month now and I desperately need to get this problem solved. Could this be some kind of ACPI or power managment driver problem? Any help would be greatly appreciated.
