It looks like Windows 11 Pro no longer includes the AC-3 codec by default, which is why your editing apps have no sound. You can fix it by installing a codec pack like K-Lite Codec Pack or by using a media player/editor such as VLC that has AC-3 support built in.
Here’s a related question with more details: AC3 codec missing from Windows 11 Pro, all my video editing apps have no sound.
I managed to fix it by installing BS Player => that installed the missing AC3 codec.

Hi, good day!
When was the last time it worked properly? Can you try installing K-Lite Codec Pack from the link below? Please select the variant type that suits your needs.
