Empty sound writes into speaker. So if you hear carefully, speaker turned on. If you connect with a2dp speaker, empty sound will write into a2dp speaker. Gecko:c00a1604ca43cf8a2061d28101aab482760b2745 Gaia:a6c29cc2f048dc08a2f008322699368b7e5cd9b0

Hardware: x86_64 → ARM
Even without connecting with a2dp speaker, you can hear "speaker" on the phone turns on. We really need to know which component did this.
I just found this also happened on current v2.1 now.
[Blocking Requested - why for this release]:

Summary: Empty sound writes into speaker → Empty sound writes into speaker, cause serious power consumption
[Blocking Requested - why for this release]: 1. Silent sound will be played all the time, even though no one is actually playing any sound 2. Power consumption is very high because speaker never turned off It looks like upper layers continuously write audio data.
Found an audio track is keep playing.

Someone is creating an AudioContext at boot time again, and should not. Break on mozilla::AudioContext::AudioContext and `call DumpJSStack()` to check what is causing this. Note that there is a spec proposal [0] to add `suspend` and `resume` methods to the AudioContext, that will allow us to solve those issues in a nicer way, but it's not stable yet.

Hi Ken, Form c10 & c12 information, I won't take this. I think gecko side won't have patch for this issue.

It looks like callscreen callSetup had been called especially after powering on!
ni Etienne, it seems system app preloaded callscreen and cause AudioContext open.

Please find the logcat.txt, and search keyword "callsetup". This logcat has been captured from boot-up. I've added log in apps/callscreen/js/index.js. window.addEventListener('load', function callSetup(evt) { window.removeEventListener('load', callSetup); - + dump('--------------------callsetup----------------------------'); CallsHandler.setup(); AudioCompetingHelper.init('callscreen'); CallScreen.init();
Flags: needinfo?(etienne)
I'm pretty sure this is related to callscreen had been loaded during boot up. Etienne, can you confirm again?

For starters, I'm not able to repro getting a refCount of 1 for any stream on bootup. However, when I open the Dialer, I then have a refCount of 1 until I kill it. Closing it is not enough. The only place where an AudioContext is created during the lifetime of the Dialer app is here: https://github.com/mozilla-b2g/gaia/blob/master/shared/js/dialer/tone_player.js#L33 When I close the Dialer app, I verified that all references to this AudioContext are released. So there should be a refCount of 0, but it stays at 1. Randell, Paul, do you know what could be going on here?

Though if the [2] is the amount of references to that object, it might explain this.
No, it's not. Can you attach the entire directory? I'm interested in the CC logs.

I guess pasting that in directly was a bad idea :/
Well, this is weird. The AudioContexts are kepts alive by the Web Audio Devtools. Are they even running ? Also, we see that they are referenced by WeakMaps (as they should if devtools are opened), so how are they kept alive ?

New PR: https://github.com/mozilla-b2g/gaia/pull/25422 Actually, let's just land this on master and rebase bug 834530. From my previous patch: (In reply to Doug Sherk (:drs) (use needinfo?) from comment #36) > I was unable to repro the consequences of the original issue. But I was able > to verify that we were indeed spawning an AudioContext on bootup.

Updated PR. The v2.1 version is slightly different but not enough to request independent review on. The only difference is this line: https://github.com/mozilla-b2g/gaia/pull/25458/files#diff-1cbdeb40c5b9f3a8e7db473bf91fc33fR77 I'll manually uplift this once it lands on master and gets approval.

Hi Doug, I've tried your patch. Yes, that fixed the original problem for boot-up. But I noticed that whenever you launched Dialer app, AudioContext will be created, as you mentioned previously. If user dial numbers and make some calls once, speaker turned on forever, it still can drain the battery, even Dialer app was been killed manually. I guess that will be another bug and needs to be followed up.

Shawn, could you please file that new bug.

Hi, I'm on latest 2.2 and I'm still suffering by those ticking sounds, during phone calls it is far from pleasant. Which bug tracks this (from my perspective) continuing problem? Thx...
(In reply to Marek Raida from comment #51) > Hi, I'm on latest 2.2 and I'm still suffering by those ticking sounds, > during phone calls it is far from pleasant. Which bug tracks this (from my > perspective) continuing problem? Thx... I'm not very sure the problem you have (ticking sounds)? But about AudioConext was created due to callscreen, you probably need to track bug 834530. bug 834530 seems to me a full solution. You may open a bug to describe your ticking sounds problem in detail (with video).
Hmmm, I'll try to record it in some quiet environment, but it is definitely related to boot-up sequence (in my case), immediately after reboot sounds are there and it is related to some Wifi/GSM/interferration, because Flight mode solves the problem...
