And both are downloading the same stream? Notice that youtube can
provide several video and audio streams, and the browser negotiate them.

Otherwise, using pulse audio in Linux, you can set up different volumes
per application. You should have somewhere a “PulseAudio Volume
Control”. Me, I have it in the multimedia menu.

The pulse audio volume control application is referred to as ‘pavucontrol’ and it typically needs to be separately installed manually in KDE (not so sure 'bout Gnome - possibly automatically installed as part of basic installation).

As noted - that application allows volume control on a per application basis.

  1. yes, both are downloading the same stream
  2. with “PulseAudio Volume Control”- a little more loudly sound.
    In the Firefox - much more loudly sound

note that the streams can be different formats one may be flash the other html5

How i can check - in which one format paly ?

By default google uses webm on chrome(ium), actually you can’t use mp4 in the html5 player or even use google-pepper-flash, I do believe there is an addon that forces mp4 (the container is mp4 the codec is h264) in chrome

the above addon forces mp4 files there are probobly other ways to do it, but I don’t use chrome(ium)
In Firefox this is easily done in about:config find and set media.webm.enabled to false, now youtube will give you mp4 files in the new html5 player, to force flash you need to disable the build-in html5 mp4 decoder.

edit.
to see what format youtube is giving you right-click on the video and select **stats for nerds **that will tell you if you are getting webm or mp4.

Then you do not know if they are the same actual stream. Notice the URL
is irrelevant.
