Bug: Audio Levels are not affected by master properties
I built a video switcher comp with expressions on each layer's opacity and audio levels turning them up or down if a slider control is set to that layer's index.
The switcher switches audio and video fine in its own comp.
When I make the slider a master property and switch it from a parent comp, the video works fine, but the audio is stuck on whatever the switch's default setting was.
You can work around this bug by linking your switcher slider to a slider in the parent comp, but this defeats the purpose of master properties as it prevents multiple instances with different audio tracks.

This should be high priority if you ask me!
