KB5015878 update broke audio in Windows but Microsoft has a fix... of sorts
One of the most recent updates released by Microsoft that has had something of an unwanted payload is the KB5015878 update for Windows 10. Many people installing the update found that it broke audio on their systems.
Microsoft has not only acknowledged the problem, it has also issued a fix. The company is using a once-rare-but-becoming-increasingly-common Known Issue Rollback (KIR) to recall the update. Sadly, it will be of no use to people who are experiencing audio problems!
