Question

I tried both with 2files and none of them support both audios,I defined with an another <audio> and problem solved!!!
what's the problem?

Answer 1

If I have understood correctly, with <source src=""> you can add 2 and more audio formats. If you did everything right, ex.:
<audio controls autoplay loop>
<source src="yoursong.mp3" type="audio/mp3">
</audio>
and your audio files are in the same folder where your html file is, everything must work, try again.
