Comment:

 OK. That seems odd to me, but we can work with it. Let's add a "My
 microphone" device to the frame. This device should be a white outline
 when the mic is off, and XO-colored when on (it's state should match the
 LED on the XO hardware). If we have access to the info, it would be nice
 to make the secondary label of the palette indicate which activity is
 using the mic eg. "In use by Record". If not, we might simply state "In
 use" or "Not in use", to add clarity to the color states.

 The secondary palette should contain a slider, just like the speaker
 device, which controls the master input level. It should also have a
 toggle, much like the speaker, which reads "Mute microphone" or "Unmute
 microphone".

 In the future, we can have a "Show audio settings" option, and might
 consider making the mute state of both speaker and microphone toggle with
 a click on the icon itself in the Frame.
