(Firefox for Android :: Media, defect)

Description

Attachment: ProtoAudioStatic.tgz

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:125.0) Gecko/20100101 Firefox/125.0

Steps to reproduce:

Android Firefox version : 125.3.0 (Build #2016017559), 9f29904153+
GV: 125.0.3-20240425211020
AS: 125.0.1
My device is a Samsung Tab A SM-T350.

I make a web server to play a list of music files. See the archive attached to get the code I put to my server.

Step to reproduce the issue.

• Open Firefox android.
• Enter in the URL the web site address https://......
• Push the Démarrer (Start) button to listen the musics playlist.

Actual results:

My playlist have 12 pieces of musics. After pushing the Démarrer button, the music start to play. After playing few pieces, the music stop. If I turn on the screen of my tablet, the music continue where it was left.

Expected results:

I was expected my playlist of musics continue from the first to the last without no interruption.
Interesting fact, if I use Firefox Focus android or Google Chrome android, I do not have this issue. All my list of music play without any problem even when my screen is turn off.

I forget to tell, the tablet should not been connected to the power pack (charging) to see this issue.

Hey Jocelyn Courcelles, thanks a lot for reporting this issue.

Have you enabled the notifications for Firefox?

Also, would you mind testing with Firefox Nightly to see if you can reproduce the bug?

You could see the Notifications option is enabled for the Firefox application.

Hi Titouan,

Thanks for your help.

The notifications for Firefox is enabled. See picture attached ( Firefox information picture from my Samsung tablet. )

I did a test with the Firefox Nightly and the issue is still present. The music hang at the third musical piece.

Thanks for your answer!

Would you mind sharing an archive or your code with some real musics, for example copyleft musics, that would help us reproduce the bug easily? 

Also, you could try following this doc to connect your Fenix Nightly to the debugger on Firefox Desktop and look into the console in case an error is visible there. Let me know if there's anything unclear here.

Please extract the exp.tgz archive to get the code.

Unfortunately, I do not have copyleft music but, you could modify the variable musics in the exp.js file and put your files under the musics directory.
Keep the following syntax for the music array variable in the exp.js.
"01 - Music title.mp3"
"02 - Music title.mp3"

Step to reproduce the issue.
The device should not be connected to the battery charger.
1 - Push the Démarrer button.
2 - Turn off the screen.
Do not use the device during testing. The music will hang before the end of the playlist.

I've tested your app on my device and I can see that the media notification disapears when the second music starts. It highly probable that playback stops because there's no foreground notification any more.

I'm not sure yet if this is a website issue or an issue on the Fenix side. I do see that the playback notification is still visibible with the second music on Chrome though.

If I use Firefox focus on my Android device, I do not see the issue. All music pieces play to the end without hang.
