This bug was introduced in #11305, as the system-generated message notifying
the user that the chat history has been cleared does not have an id.
fixes#11349
When refusing ("thumbs down" button) echo test, user is able to select a different input device. This should work fine for chrome, firefox and safari (once user grants permission when asked by html5client).
For output devices, we depend on setSinkId function, which is enabled by default on current chrome release (2020) but not in Firefox (user needs to enable "setSinkId in about:config page). This implementation is listed as (?) in MDN.
In other words, output device selection should work out of the box for chrome, only.
When selecting an outputDevice, all alert sounds (hangup, screenshare , polling, etc) also goes to the same output device.
This solves #10592
Use the former Flash client avatarURL join param to replace the name
initials avatar from the user list, chat, waiting guests and connection
status list.
It is possible to define a defaultAvatarURL at bbb-web and enable/disable it
