Volume slider still available when Silent Mode is on

[Matthew Paul Thomas]

During usability testing in August, one participant was confused that a volume slider was still available after turning on Silent Mode.

<https://wiki.ubuntu.com/Sound#phone-settings>: "Whenever “Silent Mode” is on, the volume slider should be insensitive."

<https://wiki.ubuntu.com/Sound#phone-menu>: "As with System Settings, whenever Silent Mode is on the volume slider should be insensitive."

review with ProdMgt, think this is an important issue to fix on RTM (maybe OTA)

Remember that silent mode here is used only by the 'alert' audio role. The volume slider should still show up when the active role is 'multimedia', 'alarm' or 'phone'.

Ideally the silent mode would just mean a mute for the 'alert' role, but this need further changes in ubuntu-system-settings and a few other places.

Oh, bother, you're right. So the slider does need to be available after all. I wonder if there's anything we can do to clarify what it's for. Maybe there isn't.
