"It's not more complicated, because SoundEffect and Audio *already both
exist*. If they are supposed to use the same role, what is the point of
them both existing?"

They both are intended for multimedia but the difference is on a technical level.
The Audio element is more suited for music. It provides metadata about the song it plays, reading ID3 tags from mp3 files and the like. This however makes it slow to load. The SoundEffect item instead is for sound effects. It doesn't have all the bells and whistles but is optimized for low latency. Still both are for playing audio in games/apps using the multimedia role.

If the SoundEffect would use the alert role it would be adjusted to the
ringtone value. Why would you want that? I don't want to or lower the
ringtone of the phone, I want to control the audio of the game. Having
Audio and SoundEffect on different roles would be even more confusing as
the hardware buttons sometimes would control the game's background music
(which is normally using Audio) and sometimes the SoundEffects it plays.

I do agree that games should have in-game volume controls too. But
that's quite unrelated. In the end we have two roles, alert (for
ringtones of phone calls, SMS etc) and multimedia (music player, games
music etc). Both can be controlled with the hardware buttons. This is
fine in general, but the current implementation is not good enough. As
you've pointed out there are multiple issues.

However, this discussion is getting quite off-topic on the original
issue reported in the bug. We should probably continue it on the mailing
list.

Title:
  Apps change audio output role all the time

Status in Canonical System Image:
  Confirmed
Status in indicator-sound package in Ubuntu:
  Confirmed
Status in pulseaudio package in Ubuntu:
  Confirmed

Bug description:
  To reproduce, install the app "Maroon in trouble" from the app store
  and play it a little with having sound enabled. Press the volume down
  hardware button on the phone. It will temporarily decrease the volume.
  However, whenever a new item comes into the scene, it will be on 100%
  volume again.

  Setting the system volume to 0 should keep everything at 0.

  
  Please note that this app does *not* have any code to set the volume! Also this app is one of the upstream Qt QML example demo apps, so this is really how QML apps are supposed to work (in other words, it is not a badly implemented app, but really an issue in the system)
