I forgot to add that at least recently I had option to select Audio
Backend in Chromium some time ago. Now I would have to recompile whole
modern web browser that is even more complex and time consuming that
the OS that runs the browser :-(

Is there any good reason to remove PulseAudio backend from Chromium?
What are the arguments? Is it possible to select backend like in
Firefox? All those changes and problems and confusions keep me even
more away from using Chromium.
