Example URL:
https://www.chatzozo.com/bug/

Steps to reproduce the problem:
1. https://www.chatzozo.com/bug/  Open the link
2. Log in as guest user/register user. Choose any one of the room to log into the chat room.
3. Click the MICROPHONE icon to record your voice. Once you done recording, click he square black stop button to send the voice message automatically in the room.
4. Once you see a voice note on the screen, try to play it. It won't play any voice messages. This is the bug, which happens only on android chrome browsers.
5. But if you, use the direct link of the chat room "https://indianchat.chatzozo.com/chat.php " you can record your voice and send them into the room. So, i'm pretty sure this is the iframe tag permission issue.

What is the expected behavior?

What went wrong?
Users who use chrome browsers can't record voice messages due to allow tag permission in the iframe. 

I have tested it with all desktop devices and it works fine in iframe mode and even i checked with firefox browser on android phone. It works fine on the firefox browser. So chrome is the one making this issue.

Did this work before? Yes It worked on last version of chrome beta.

Is it a problem with Flash or HTML5? Both

Does this work in other browsers? Yes

The weird part is, i created a bug report last time, then it worked fine on the beta version of the chrome. But, once you guys released beta as sable version. It does not work. very very weird isssue...
