I think that's actually a pretty useful addition.

Thanks for your feedback. I've made the changes, and will push them shortly.

This looks good, I think it should be merged reasonable soon.

For this PR the most sensible option to me seems to set the minimum in the UI to 0%, this way it is possible to "mute" dolphin without using keybindings. We should keep the unmute on change volume behaviour for now. After this PR is merged a followup PR is made which deals with the UI.

My proposal for the UI:

• When a user mutes dolphin using the keybinding the UI slider stays on the same place but the percentage gets replaced with a muted icon and we don't unmute when the volume is changed.
  • This allows for a way to change the volume without unmuting and we have UI feedback.
• Lowering the volume to 0% should not show a muted icon to prevent confusion since there will be no good way to tell if it's at 0% or muted.
• A graphical overlay is possible I think but is limited to text only.
  • Another way of doing this is to add a volume slider in the main UI instead of a separate window. Personally I'm not really fond of this idea. I'd rather avoid moving parts in the main UI.

Note: We can't add an extra button unless the layout is changed, which I'd like to avoid.

Regardless of how people want the very specifics of this feature to work, are we agreed that this should be added? I think it's a nice feature, and it would be useful, especially for streaming Dolphin.

I would be ok with adding this feature. It won't get in your way if you don't want to use it and it's useful in certain scenarios.
