This happened on a appr.tc call with audio and video. I unplugged my apple earpods and the tab crashed. I have not been able to reproduce this yet.

Hhmm since crash report is empty is there any chance to get logs (MediaStreamGraph:4,cubeb:4)? I know it is sporadic I am asking just in case. I will try to repro here as well.

I am not able to repro. Can you please try to repro with the logs activated?

I have tried reproducing this in 56 beta using appear.in. On the 41st plug event audio and video froze but there was no crash. After a page refresh a CubebAggregateDevice appears in the gUM audio input list. I then replugged another 59 times, and still no crash.

Logs including the freeze. My default log levels are perhaps a bit aggressive with the log levels. I stripped out all the [Socket Thread] activity to get the size down.

padenot tells me this should be fixed by bug 1399905.
