Missing audio track

[Kraltt]

Hello,
I'm working with Premiere Element 2018 and I would like to make a film with videos from an old SONY camcorder with sequences composed of 3 files in .mpg + .xmm + .modd.
I can play them without any problem on my PC W 10, but when I want to place it in the editing bench, the audio track doesn't appear .
Thank you for helping me on this problem.

I don't know enough about your footage to say what to do.  If it were me, my first guess would be to use the capable and free program called Handbrake to process or "convert" to a more editable format.

Thanks, but what I don't understand is that I don't have a problem with my Premiere Element 2009 version and not with the 2018 version...

Dont you see an audio attched to the video or dont you hear it from the timeline> be more specific as many scenarios are possible,

Which camera are the files from.

Post screenshot of just the mpg file in Mediainfo in treeview here on the forum.
