Issue with reproduction of recordings in wav

Hi all,
I use ubuntu mate 18.04
I have a problem with the reproduction of recordings in wav format. Pressing play only sounds a loud noise and if the file is 10 minutes shortens it to 8 seconds.¿cuál podría ser el problema? Thanks

It’s probably not a valid WAV file.

Try installing MediaInfo (available in the Ubuntu repository). Open the files with MediaInfo and it will display information about the actual file format.
