No audio for videos on some (!) SmartPhones when MP3 codec is used?

Occasionally I send some videos to other people on WhatsApp.

If these MP4 videos contain (beside MPEG-4 video codec) an lame-MP3 encoded audio track then some (but not all) people cannot hear the audio (only video).

As far as I can see these people are using an iPhone.

Can it be that iOS on iPhones does not understand MP3 audio tracks?

What else can be the problem?
