Platform: 9202.18.0 (Official Build) dev-channel swanky

Example URL:
music.google.com, youtube.com

Steps to reproduce the problem:
1. Plug in headphones
2. Go to site that plays audio
3. Hear audio through the computer and not the headphones.

What is the expected behavior?
Audio to play through the headphones.

What went wrong?
Audio played through internal speakers not through the connected headphones.

Did this work before? Yes  57.0.2970.0 I believe, I know it was the one before this current update.

Is it a problem with Flash or HTML5? N/A

Does this work in other browsers? Yes
