Well, I'm very confused with all the audio stuff: ALSA, PulseAudio,
It's quite simple, actually. The graphics chain goes like this:
some app (that wants to display a window) talks to:
kwin (the window manager) which talks to:
X11 (the graphics server) which talks to:
intel/radeon/nouveau kernel module (the hardware dirver) which talks to:
In complete analogy, the sound chain goes like this:
some app (which wants to play sound) talks to:
phonon (the sound manager) which talks to:
pulseaudio (the sound server) which talks to:
ALSA (the hardware driver) which talks to:
If I go to "System Settings -> Multimedia -> Phonon"
I see only one
device "Internal Audio Analog Stereo". I think that that means that
Pulseaudio is OK, right? If I click on `test' I heard correctly the
sound. If I try to configure the audio through Amarok I get the same.
You can check if pulseaudio is working by playing something in, say, Amarok
and running top in the console --- pulseaudio should be doing something.
Alternatively type "ps aux | grep pulseaudio" in the terminal. If it's
you'll see it.
Also, it should be enabled by default, so if you didn't disable it on purpose,
it should be there.
BUT, if I have Amarok running, then I have no sound in Firefox, and
viceversa, if I have Firefox with a video running, then if I launch
Amarok the audio is stopped, and no audio comes from Amarok, only from
Both firefox (I guess you actually mean flash-player) and Amarok should be
configured to use pulseaudio for this to work properly. This is basically
configured by default, unless you have some weird config inherited from the
I am not sure why it doesn't work for you. Maybe it is something weird related
to flash player or whatever. If everything else works and if you can live with
it, leave it be (until you decide to do a clean install sometime in the

the audio correctly in the alternate user (mstorti2) then I will
switch all my stuff to it, and I think almost all my problems are
Well, I guess that's probably the easiest way to solve (actually, work around)
the problem. :-)
