Thanks for reporting this. Is a crash report visible in about:crashes for the crash? If so, a link to the crash report would be appreciated. Also can you please attach a copy of the data from about:support?

Running Firefox with audio logging enabled may also help narrow down the cause of this, so if you can run:

MOZ_LOG=cubeb:5 MOZ_LOG_FILE=firefox.log path/to/firefox

and attach any firefox.log* files produced that'd be very helpful. Thanks!
