Gain and mute are read straight from the node's media settings, so the strip and the component's own inspector fields are the same value — there is no second, hidden level.

A channel is audible only when it is not muted, not silenced by another channel's solo, and actually has a source. The master bus meter lights when at least one channel is live and the master is not muted.
