1423739 - Firefox tab crashes switching audio device during WebRTC call

Status: NEW

(Core :: Audio/Video: cubeb, enhancement, P3)

Description

[Paul E. Jones]

Whenever I call into a WebRTC call on appear.in and then switch the preferred audio device from my desktop speakers to my headphones, the tab will crash.  I used to do that with FF56 and did not have this issue.

Can you go to about:crashes then click on the crash ID, and provide the link to the crash report?

I have a couple for you:

One is from a call on 6-Dec-2017 and one from 29-Nov-2017.  Each one is where I attempted to change the default speakers on my machine during a WebRTC call.
