Hello, well i have a Beats Audio, an Intel HD (IDT92HD91BXX) and I'm usign KDE. When i listen some music, or viewing any movie, in general listen any kind of sound, if another sound is played in paralell with the actual then a high noise crash (always at high volumen, not metter that the hadware volumen is set to low), for example, if arrive a new email, if a new message is icoming, if i want to delete something from my filesystem throw dolphin (the sound of the delete dialog). This is more explained at bugtracking in debian... in there are the pulseaudio logs and configuration files.... https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=782730
This sounds like a problem with synchronizing hardware and software volume changes when using flat volumes. This is a problem that can't be solved perfectly. You can try to mitigate it by tweaking the deferred-volume-safety-margin-usec and deferred-volume-extra-delay-usec variables in /etc/pulse/daemon.conf. Or if you are not a fan of the flat volume feature, an easier fix is to set flat-volumes=no in daemon.conf.
Uff thanks, it's works, with flat-volumes in off.... but if not all system work with flat-volumes, why is set to true by default??

It's true by default, because Lennart (the original PulseAudio author) thought that flat volumes were a great idea, and there are still PulseAudio maintainers with that opinion. If someone submitted a patch that changed the default, that might get accepted. I haven't submitted the patch myself, because I dread the discussion that would ensue. You could try to convince Debian to change the default. Ubuntu already disables flat volumes by default.
