No Sound when importing m2ts file with Dolby Digital audio into Premiere PPro

I know that this problem was discussed in another thread already but I post it here anyway.

I am currently on PP 25.6.3 on a Windows 11 PC

When I am importing a .m2ts file with Dolby Digital audio there is no sound in PP. When I double click on the .m2ts file OUTSIDE PP the video plays back perfectly with picture and sound in Windows Mediaplayer.

Any solution?

Thanks, Ann.

I am a bit puzzled now. Why would one file have sound when imported and another one stays mute when imported (see attached screenshots in my second message. Also I am pretty sure that I do have the AC-3 codec installed on my Windows 11 machine.

Try downloading them from the camera again?

Why?

The problem is that both .m2ts files do have AC-3 audio. In one case the audio is not imported into PP, in the other case it is. If I play those .m2ts files outside of PP both videos are played back with sound.

W11 does not support ac3 audio any more

You need to convert the files (eg Prores) or install the ac3 codec.

I found that certain .m2ts files are imported with sound, others without. I have made two screenshots. The first shows the media info of the file which is imported without sound, the second screenshot is the one which is imported with sound.
