AC-3 (Dolby Digital) codec no longer included with Windows 11 version 24H2



 Microsoft Support:

AC-3 is an audio codec that supports multi-channel (“surround sound”) audio. It's also known as Dolby Digital.

On versions of Windows prior to Windows 11, version 24H2, the AC-3 codec is included.

Beginning with Windows 11, version 24H2, the AC-3 codec is no longer included with Windows. However, many device manufacturers will pre-install an AC-3 codec. Also, if you upgrade to Windows 11, version 24H2 from an earlier version of Windows, the AC-3 codec will be retained. In these cases, you will still be able to play files encoded with the AC-3 audio codec.

I haven't used Dolby AC-3/AC-4 Installer - MajorGeeks.

Windows 11 23H2 Build 22631 or earlier already contains native Dolby Digital supports. Basically, just install the AC-3 files from the previous version onto the 24H2.

Yes, I am still actually on Beta Insiders 23H2 but just wanted the CODECs on the system regardless. So it seems like AnWave covers AC-3. The MajorGeeks appears to be Windows Store apps which are Microsoft's CODEC's as it's in two appx bundles, one is for Dolby Digital Plus and the other is AC-4 so for the TrueHD, one I guess could use K-Lite CODEC Pack which has both AC-3 and TrueHD.
