Window -> Mute This Tab/Mute Other Tabs are always greyed out

Steps to reproduce:

1. Play any media with audio in Orion
2. Go to Window -> Mute this tab/Mute Other tabs
3. Notice that the buttons are always greyed out, even if there is something to be muted
4. Right clicking the tab and selecting Mute Tab works as expected

Expected behavior:
Window -> Mute this tab/Mute Other tabs should be able to be clicked and they should function as their names would suggest.
