1222185 - music app audio playback gets interrupted

Status: RESOLVED WONTFIX

(Firefox OS Graveyard :: Gaia::System::Audio Mgmt, defect)

Description

[Jovan Gerodetti]

User-Agent: Mozilla/5.0 (Mobile; rv:44.0) Gecko/44.0 Firefox/44.0

When unlocking the device, switching to an other app or receiving a new notification while the screen is of, many times the audio playback just stops. Also the control "widgets" in the notification tray and on the lockscreen disapear. As soon as I return back to the music app the audio playback continues.

This isn't a music bug. It's arguably an audio channel issue, or more likely, whatever component is in charge of that mind-boggingly annoying text-to-speech whenever you switch apps.

Comment 2

[Jim Porter (:squib)]

Not sure if this is happening on 2.5 or not, but this needs to block. Ideally, the solution is to get rid of the text-to-speech because I hate it.

Comment 3

[Jovan Gerodetti]

I don't hear any text to speech, but I experiencing this issue on 2.5.

Comment 4

[Jim Porter (:squib)]

[Blocking Requested - why for this release]: This is happening in 2.5 according to comment 3 (hopefully these are the same issue in 2.5 and 2.6). It's also extremely bad, since it effectively makes the music app unusable.

Hi, Evan,
It seems related with the audio competing policy.
Could you help to take a look?

Comment 6

Hi Jovan,

I cannot reproduce the issue in this build[1].

Music app can continue to play when unlocking the device, switching to an other app or receiving a new notification. But screen unlock sound will stop music, we're fixing it in Bug 1214908.

Could you provide clear STR to help me reproduce the bug?
Thanks.

Hi Evan, 

I still have a outdated build [1].
After you mentioned the issue with the unlocking sound, I tried to reproduce the issue again.
As far as I see, the problem only occurs if the app I'm switching to also tired to play some kind of audio.

The problem with receiving a notification I think was caused by Bug 1222059. 
1. I had Telegram Messenger in the foreground. 
2. I locked my device. 
3. I received a new message and the application triggered a new notification. 
4. The notification instantly turned on the screen, due to Bug 1222059 the app thought it's in the foreground and also played a sound.
5. Music app playback got interrupted.

Hi Jovan,

I follow the below steps to reproduce the bug. But I use pre-installed Messages app, not Telegram Messenger.

In the step 5, we will turn the Music app playback's volume down and then turn it's volume as normal.

That is not interruption. That is fade-in and fade-out effect we defined in the spec[1].

So this is not a bug. It's a feature.
