How to play audio in background with firefox os?

Question

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

\"permissions\": {
    \"audio-channel-content\":{\"description\":\"Use the audio cha         


        

Answer 1

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';

Answer 2

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.
