How to play audio in background with firefox os?

问题

In my manifest file I've add the audio-channel-content in permissions:

"permissions": {
    "audio-channel-content":{"description":"Use the audio channel for the music player"}
}

In my index.html I've got an audio tag like:

<audio mozaudiochannel="content" preload="none" src="http://my-stream-url"></audio>

I can play my audio stream during 2mn:

• The first one when the phone is unlock.
• After 1mn my phone auto-lock the screen and it continue playing for another minute.

Does it possible to play this audio stream more than 1mn after the lock?

Thanks in advance.

The code and permission block you have are correct and I can confirm it is working in Firefox OS 1.1. You can also do the whole thing in Javascript:

audio = new Audio();
audio.preload = 'none';
audio.mozAudioChannelType = 'content';

It's because the wifi is closed after screen shutdown (auto-lock)?

Are you using the dev version of gaia? Wifi is set to always connect in product version.
