Steps to reproduce the problem:
1. Open a tab and play audio (Could be any YouTube video)
2. Open another tab
3. Click the speaker icon

What is the expected behavior?
1. Audio from that tab should mute
2. The speaker icon should indicate that audio is muted (suggest line through speaker much like YouTube)

What went wrong?
It's not *wrong*, it's just a feature request.

Did this work before? No
