Because Flash player didn't work in the past. When flash started, it
blocked the output of all other things among.

As requested, I moved the pulse folder somewhere else and remerged
pulseaudio as well moved /etc/asound.conf somewhere else as well.

No sound!

I have the dumb feeling that one process is blocking the output, I hear
in my headphones the white noise of my system, which wouldn't be there
if the soundcard hadn't been initialised.

Is there a way to find out which applications might make use of the
soundcard right now?!

It's more simple than that: if you see the bars movind in the mixer
application, some sound should be made.

Probably with strace or a similar tool; however, let me see first if
I'm understanding the problem. This is a laptop? If so, the sound
works without headphones? The internal speakers work?

Also, can you please post the output of "pactl list"?

Also, in alsamixer not only set the bars up: make sure the control is
not muted (it has an "M" at the bottom if muted). You can mute/unmute
pressing the letter 'm'.

I opened the browser, and I hear music!!!! WOW!!! but the pulsemeter
playback is death. It does, but not through pulseaudio

so with alsa directly we have sound, but not with pulseaudio

I think I see the problem: the sound is getting through the digital output, not the analog one (near the end of pactl output). You need to set the analog output: pactl man page will tell you how (sorry, left the laptop at the office and I'm writing this on my phone). It's also possible to do it with gnome-sound-settings, in the hardware tab (if I remember correctly).

Good luck.

pavucontrol is your friend. It lets you configure your sound devices
current profile, and also set the fallback (default) sink.

Also, if flash didn't work previously, that's because it was not using
PA (or alsa default device), it was hardcoded to use alsa device hw0,
so they "forcefully" used to use ALSA. Since PA has control over the
sound device (since PA is the mixer, not ALSA), flash couldn't use it,
thus no sound.

I reaffirm, you should use all 4 blocks of configuration in your
asound.conf. It will "create" the PA virtual device and also set it as
default for the system. This way, ALSA software will output to PA too.
