Why doesn't the audio tag work in safari?

Question

safari

<audio src="test.php"></audio>

test.php is now like this, although I changed it 10 times, it always works absolutely everywhere on desktop and mobile, except for safari, it fires an onerror event on the audio tag

header('Content-Type: application/octet-stream');
header("Content-Disposition: attachment; filename=\"".$_GET["id"]."\"");
echo file_get_contents("https://... не важно");

Answer 1

There is an answer at the end =)
