### Issue 2 - Turning off speaker, changes Mute property and modifies Volume value

Clicking on Speaker tile, Speaker is displayed as "Mute: true" and "Volume: 1%"

### Issue 3 - Speaker cannot be turned back on

Clicking on Speaker tile, Speaker remains as "Mute: true" and "Volume: 0%"

Opening modal menu and clicking "On" button, Speaker tile still shows as "Mute: true":
