Hello!

Sorry for the slow response here...

I can confirm that removing audio_capture_enabled from
master_preferences.json solves this issue.  Fix pushed in
5ee1c0459eebdd3b7771abaeab0f0b52ff86fdd5.

For existing Chromium profiles, you will need to close all browser
windows and run

 sed -i 's/"audio_capture_enabled":false/"audio_capture_enabled":true/' \
     ~/.config/chromium/Default/Preferences 

...to get the new default.

Thanks!
