[GitHub issue by davidflanagan on 2012-05-29T18:54:08Z, https://github.com/mozilla-b2g/gaia/issues/1514] The volume control buttons on the phone are currently implemented in a very hacky way. Both Gecko and Gaia listen for volume key events. Gecko actually changes the volume when it sees them, and Gaia just updates the on-screen volume indicator when it sees the events. This works if Gecko and Gaia do exactly the same thing for each event. The bug is that Gaia currently implements auto-repeat functionality, so you can press and hold the volume up or volume down buttons. And Gecko does not implement this, so the two can easily get out of sync. Ideally, gaia would have a way to set the system volume, or gecko would have a way to notify gaia when the volume has been changed, so only one is in charge of the volume. But failing that, gecko needs to implement the same autorepeat functionality that gaia has.
[GitHub comment by timdream on 2012-05-30T09:48:38Z] Almost all the issues that related to volume is because of this one. @jammink @tonychung please link (and close) there issue to this issue, thanks.
[GitHub comment by tonychung on 2012-05-30T14:17:13Z] Is there a bugzilla bug that someone can add here that tracks the work on the gecko side?

Sound manager set audio volume into Gecko via settings with observer event. https://github.com/mozilla-b2g/gaia/blob/master/apps/system/js/sound_manager.js#L98 And sound manager get this observer event to set current volume too. https://github.com/mozilla-b2g/gaia/blob/master/apps/system/js/sound_manager.js#L20 The problem may occurred on synchronization between "https://github.com/mozilla-b2g/gaia/blob/master/apps/system/js/sound_manager.js#L20" and next repeating key event for changing audio volume. Once repeating key events are faster then observer event then bug is appeared.

This bug is extremely old. I wonder why it was not closed? (In reply to Marco Chen [:mchen] from comment #3) > The problem may occurred on synchronization between > "https://github.com/mozilla-b2g/gaia/blob/master/apps/system/js/ > sound_manager.js#L20" and next repeating key event for changing audio > volume.
