Steps to reproduce the problem:
1. Chromebook was updated to version 70
2. Icon no longer appears when the volume is muted.

What is the expected behavior?
Icon representing a speaker with a line through it to indicate that the volume is muted should appear in the bottom-right of the taskbar when the volume is muted.

What went wrong?
The icon does not appear.

Did this work before? Yes 69.0.3497.120

Chrome version: 70.0.3538.76  Channel: stable
OS Version: 11021.56.0
Flash Version: 31.0.0.122 

It is no longer clear to the end user that the chromebook is muted, and there is no visual difference between muted and non-muted. This could potentially result in embarrassing situations or make it more difficult to tell whether or not a pair of headphones is plugged into a loose jack port.

There is no reason to obscure this important information from the user, and is a regression from the previous version that results in a loss of ease of use.
