Bug 832170 - DTMF lower volume -> When fixing Bug 832170, represent this bug. So I add below source ''' this._audio.mozAudioChannelType = 'ringer'; '''

Comment on attachment 719335 [details] Patch URL to pull request_8369 Don't do this. There's side effort to promote the channel to ringer or notification.

Isn't this bug a high priority? For the case when the sound is muted (or set to silent) using the volume controls, the keypad tones are still played at their full volume (this._audio.volume = 0.5; -- keypad.js#L53) -> a very undesirable UX situation.

I think this is a regression of bug 784184. it was fixed back then. vivien, can you take a look? i heard you touched audio last.

There're several workarounds we had considered. 1. Just implement silent mode to achieve comment 3. See https://bugzilla.mozilla.org/show_bug.cgi?id=819842 Side effect: You still couldn't change the volume of DTMF tone. 2. Just implement short audio adjust See https://bugzilla.mozilla.org/show_bug.cgi?id=825970 Side effect: This is general change in sound manager and I'm afraid it would affect other volume. 3. Looking forward backend API change in bug 853101. (Very impractical cuz it's big change) This one and similar issue is raised again and again, there's just no right answer to this bug now, I am c.c.ing some audio backend guys.

Deassign myself first. Will keep tracking.

Could we start by doing these two things and see how well that works? I don't think we'll ever find a perfect solution, but these two things should be fixed no matter what. After that we can reassess what we should do. > 3. Looking forward backend API change in bug 853101. (Very impractical cuz > it's big change) Yeah, I agree, I don't think we should block on that bug here.

Though bug 819842 and bug 825970 are both minus-ed I am going to do one or both of them to lessen the impact of this problem.

I encounter a problem: I found the sound of DTMF audio isn't firing audio-channel-changed event to system app so we'll never know the user is pressing dialer keypad in system. Trying to investigate it's a gecko problem or not.

This issue is happening in v 1.0.1 as well. I cannot lower the dial pad volume. Unagi Build ID: 20130417070205 Gecko: http://hg.mozilla.org/releases/mozilla-b2g18_v1_0_1/rev/6bac24e14538 Gaia: 2d048a9bdae54e4ec7d48326c2130591c8b869b6

My work in bug 819842 makes it possible to mute the keypad sound via volume rocker. I think it's worthy to close this and use https://bugzilla.mozilla.org/show_bug.cgi?id=825970 for tracking "cannot change a short playing audio".

Alive, should we mark this as fixed on branches then?

Mark doen. See also https://bugzilla.mozilla.org/show_bug.cgi?id=866036

This issue seems to be fixed only for V1 train and not for v 1.0.1.
