Steps to reproduce the problem:
Try to play media file encoded using AC-3 codec

What is the expected behavior?
Chromium should support AC-3 decoding

What went wrong?
Chromium doesn't support AC-3 decoding

Did this work before? N/A 

Does this work in other browsers? N/A

Chrome version: 60.0.3076.0  Channel: canary
OS Version: 
Flash Version: 

Finally, on 19.03.2017, the last of Dolby's patents over the AC-3 codec expired. You can read more about it on https://ac3freedomday.org (cached page: https://web.archive.org/web/20170401170436/https://ac3freedomday.org).

This means that now Chromium team can enable full AC-3 support (AC-3 decoding) without need to pay royalty.
