Microsoft confirms a second Home windows 11 audio bug this month

On this assist web page for optionally available September replace KB5124010, Microsoft notes this as a identified challenge labeled “Purposes which require AC-3 audio decoding would possibly shut unexpectedly”:

After putting in this replace, some purposes that use AC-3 (Dolby Digital) audio decoding would possibly fail to launch or shut unexpectedly when sure audio options are used. This challenge primarily impacts legacy purposes that depend on Home windows built-in audio decoding. Most trendy purposes aren’t affected.

In response to Microsoft, most customers seemingly gained’t encounter this bug, because it impacts “legacy” apps and video games that depend on Home windows’ built-in audio decoding. And to be clear, this challenge is unrelated to the opposite September replace challenge involving damaged USB audio.

This AC-3 downside persists even after putting in optionally available replace KB5124010 on Home windows 11 25H2, and upgrading to Home windows 11 26H2 doesn’t resolve the difficulty both. The issue is situated deep within the system and impacts a number of Home windows 11 variations as a result of all of them share the identical code base.

Microsoft is conscious of the issue and dealing on a repair:

Microsoft is engaged on releasing a decision for this challenge in a future Home windows replace. We’ll present an replace when extra info is accessible.
