Why are newly added music files not played on my Huawei p30 lite?

I copy my CDs to the PC and the files are completely saved there. If I then copy the files to the mobile phone or the SD card in the mobile phone, the files are incomplete. One second, if any, of the title is played. The problem is with all the music files that I drag onto my phone.

In which format do you save them on the phone? The cell phone may only be able to play mp3. They may be in a different format on the PC. (Wav.)

That should be the MP3 format. I have the same problem when I convert it using the media player. The data is saved as an MP3 file, but I still can't play it, at least on my mobile phone.

Then go to the files on properties and have a look. If you copy the CD directly to the PC, they will always be in WAV format. The media player or VCL player can handle it. Not the cell phone. I use an extra converter for this (e.g. Format Factory)

Thanks for the star
