unexpected audio policy user experience

[kevin gunn]

discovered this in testing today, image #78

play a song from "Music" scope in dash
navigate away to "video" play a video
the music & video audio play together
I would have expected music to remain "paused" during video playback

It will be the case once oxide switch to media-hub bug 1249387

[David Barth (dbarth)]

It can't be rtm14 as far as i can tell.

The problem is that MH does not have a way AFAICT of letting an app express the type of audio environment it wants.
So it mostly multiplexes stuff it receives.
There is no way either, and rightfully so, of stopping a stream from an app, unless it's your own stream.

So how could we stop the stream?

[kevin gunn (kgunn72)]

the tag is really a suggestion, i think this is one of those bugs on the edge, i could see it argued in or out of rtm.
worthy of some LT discussion imho.

[Bill Filler (bfiller)]

this isn't a webbrowser bug either way though. there are separate bugs filed to have browser use media-hub but that's not the condition you are describing.

[Bill Filler (bfiller)]

sounds like you are looking for a way for the media-hub to add some policy around requests being made to it from multiple streams. will add a media-hub task for it.

[Ricardo Salveti (rsalveti)]

Media-hub can only be involved in this once the browser is actually using it when playing audio/video. The main problem we have atm is that the browser is talking directly to pulse, and not going via media-hub, so there's no simple way for the app to know that it has to stop/pause.
