ios - HTML5 audio playback over HTTPS on safari IPhone 4.3

Question

I have written a simple HTML code to play an audio file using the HTML5 audio tag on IPhone.

<audio controls="controls" autoplay="autoplay">
<source src="http://192.168.1.130/ab.wav>" type="audio/wav" preload="auto"/>
Your browser does not support the audio element.
</audio>

The above code works perfectly fine over safari. The problem comes when I change the Source URL from HTTP to HTTPS.

I started getting "This movie could not be played" error message.

I am using a certificate chain which is as follows:

VeriSign Trial Secure Server Root CA - G2 -> VeriSign Trial Secure Server CA - G2 -> ucbu-aricent-vm200

The certificate of the Root CA (above) is not available in Safari by default.

So I had attached the certificate for the certificate authority (both Root and Intermediate) to an email, and then added them in IPhone by clicking the attachments in the email.

But still I see that the SSL Handshake fails when Safari created a TCP session to transfer the WAV file.

NOTE: The SSL handshake goes successful when the TCP session is created to fetch the HTML file from the server. I had compared the network packets of the SSL handshake of HTML and WAV file scenarios and both of them were identical.

Answer 1

This was mentioned above by ceejoyez and again by the OP (Thank you both!), but I almost missed it as it wasn't an actual answer:

If you are serving the content over https you need to have a valid certificate or it will not play on iOS devices (or on Safari on a Mac).
