Ubuntu – Sound is not working correctly on Ubuntu 12.04

12.04pulseaudiosound

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
Sound Settings

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:

It seems like I'm unable to comment, so I'm putting my comment into this answer.

Could you open a terminal (Control + Alt + T by default) and enter the command alsamixer? You should see a bunch of volume levels. Make sure they are towards the top of their bars and unmuted ("OO" is unmuted, "MM" is muted at the bottom of each bar).

If it doesn't look like anything's wrong, could you post a screenshot of the alsamixer window?
