How to implement validation of audio files during download?

Question

Yii

In rules I add:

[
    ['fileAudio'], 'file', 'maxSize' => '41943040', 'extensions' => 'mp3, wav, wave, mp3, amr, m4a, 3gpp, 4gpp, 3gp, wma'
]

But the download fails. Everything is fine with images, the rules differ only in extensions. I check on mp3 files.
Thanks in advance.
