The console mute line feature works as a latched mute button for a particular
resource. It is important to note that when the resource is
selected while muted, the console automatically unmutes the resource.
The mute all function
mutes every line
except for the currently selected lines(s). It is
located on the Console Widget on the lower left-hand side.

Unmute all simply unmutes all resources. Sometimes referred to as "RX All".
It is located on the Console Widget, below the mute all button.
