Bug Description

My webapp "KlassikRadio" does not work any more.

Opening the webapp opens the window as expected. Nevertheless the audio keeps dry. The phone remains silent.

I have played around and found out that the option: --enable-media-hub-audio breaks the audio stream. When I take this option off the KlassikRadio.desktop file it works.

I am using:

current build number: 387
device name: krillin
channel: ubuntu-touch/rc-proposed/bq-aquaris.en
last update: 2016-07-16 08:46:05
version version: 387
version ubuntu: 20160716
version device: 20160606-ab415b2
version custom: 20160701-981-38-14

Nevertheless this issue is around since several weeks. I assume the option still works with OTA11 but I can not proof this right now.

Can someone have a look? Is the option not available any more in the latest release or is it just a bug? The option is still mentioned in:

https://developer.ubuntu.com/en/phone/web/ubuntu-webapps-guide/

Thanks for your support. If someone wants to test this, the KlassikRadio app version 0.30 has this option enabled. I will put another version (0.31) in the store in the next days before OTA12 comes along, where I will take this option out and replace it with "keep-display-on" in the apparmor-file.

The keep-display-on solution is not nice. Are there any other options I could use alternatively?

I confirm this issue with my "uFip" webapp.
Also I confirm this is a regression from the OTA 12 development cycle: I flashed back my Nexus 4 to OTA 11 and it started working again.

Here are some logs that may be interesting:

same on MX4 ota 12 and M10 rc-proposed, making a music webapp and enable-media-hub-audio works on neither.

Since OTA 13 this is even worse: now the webview of my webapp just crashes when the audio playback starts.
Before there was no sound but it was possible to browse the website. Now there is a white page with an error message and a refresh button.

As before, removing "--enable-media-hub-audio" fixes everything, except (of course) that the app has to remain focused to continue streaming.

I tried to play around with alternate webapp containers, but without success.
Is there any known workaround? I'm getting bad reviews on my app because of this bug…
