This warning is only shown to the user (on Android) if headphones are plugged it.
We too could display such a warning by triggering a corresponding snap- decision from indicator-sound. With our current notification-system we have all needed means for this in place. But what icon, summary- and body-text should it display? What labels should be used on the buttons. How should the phone (indicator-sound) behave if the user selects "Cancel"? How long should it (indicator-sound) remember that user- choice? Until headphones are unplugged and plugged in again? This needs some good thought and "user-journey" from Design. What we need on the side of indicator-sound is a way to determine, if a headphone is currently plugged into the phone or not. I don't know the audio-stack well enough to answer this. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unity8 in Ubuntu. https://bugs.launchpad.net/bugs/1232633 Title: [system] Changing volume doesn't show feedback on the phone Status in Ubuntu UX bugs: Fix Committed Status in “unity8” package in Ubuntu: In Progress Bug description: Not an indicator of volume status when it makes adjusting volume (Nexus 4) <https://wiki.ubuntu.com/Sound#volume-keys>: "In addition, any of those keys/buttons should play a subtle noise for you to gauge the volume, and display a confirmation bubble with the icon of the primary sound output at the current volume, a volume bar, and accessible text “Sound muted” or “Volume {X}%” (for example, “Volume 75%”)." **Update** For EU regulations: When listening to music/audio sources and the volume is raised above a certain threshold a warning must be displayed to user.
