Per my investigation, the root cause should be as the same as bug 1006356. Because the visibility is affected by hidden_telephony audio channel. Once we encounter the bug 1006356 issue, the hidden telephony audio channel is occupied.

I try to disable the toneplayer init in keypad.js, and I can *not* duplicate this issue. Please see the comment 67 of bug 1006356. https://bugzilla.mozilla.org/show_bug.cgi?id=1006356#c67

    //TonePlayer.init('normal');
    //var channel = this._onCall ? 'telephony' : 'normal';
    //window.addEventListener('visibilitychange', (function() {
    //  TonePlayer.setChannel(document.mozHidden ? 'normal' : channel);
    //}).bind(this));

It can work on my device with the latest Gaia SW.

Got it. I'll re-test it after bug 1006356 being fixed.
Star, thanks for your help.

Verified on build 20140518164003, audio can be played in background after a phone call, and the volume control works fine too.
