First of all, sorry for the tittle. English isn't my native language, and I can't find a word to describe the strange behavior I'm getting here.
In the most simple explanation, is like sound keeps going down and up again...
Think in a kid with that old radios that have a circled volume button. Think like these kid keeps "turning" the volume button. That is the behavior I'm getting here.
At first, I believed that it was a pulseaudio issue, but, it isn't. I followed the wiki part I think that should be my problem, but it didn't work.
After that, as I'm using XFCE, I didn't really need pulseaudio, so I removed it and stays with a clean alsa, hopping that will fix my problem. Sweet mistake.
It really looks like a kid looking for trouble. I believed it worked, and, suddenly, here is the same issue again.
BTW: I have a full-upgraded testing system (yeah, I upgraded to testing hopping for new pulseaudio version which fix the issue), no pulseaudio at all, just xfce, started with startxfce.
What can I do to fix this? It's extremely annoying... sometimes I just want to throw my laptop in the wall because of this.
Any extra info you need, please, tell me.
Thanks in advance

My alsamixer is like this:
And here is a video with the sound behavior.
