I know this is my own fault. But what i did was this
first i wrote this command 'sudo apt-get remove pulseaudio' and then i wrote again 'sudo apt-get install pulseaudio' and now the sound doesn't work properly

And the Indicator doesn't work either, it's just grayed out. The shortcuts are not working either.

Alsamixer is working, and this is the only way i change change the volume at the moment:

jeggy@jeggy-XPS:~$ cat /proc/asound/cards
