Users of Windows 11 24H2 are encountering an unexpected audio quirk that has raised eyebrows, particularly among gamers. Reports indicate that sound levels can spontaneously surge to a startling 100 percent, creating an unwelcome surprise for those immersed in their gaming experiences. Notably, this issue appears to predominantly affect systems equipped with gaming-oriented hardware.

Identifying the Problem

Microsoft has acknowledged the existence of this bug, pinpointing its occurrence under specific conditions:
