Steps to reproduce the problem:
1. Connect Bluetooth headset (with mic support) to ChomeOS
2. Try a hangouts or other form of phone call
3. 

What is the expected behavior?
Audio can be heard over the headset but no audio is transmitted.

What went wrong?
It looks like the HFP implementation (which should power such Bluetooth calls) is only allowing one way audio traffic. It is not able to send audio back from the headset microphone back to the app. Is this expected from ChomeOS? Does ChromeOS support HFP profile or mic input over bluetooth in general?

Did this work before? N/A 

Does this work in other browsers? N/A
