Sound - no devices, no sound

Hello everyone,
I am sorry to create a new thread about sound problems, but I'm desperate and none of the other threads has helped.

When I found out my netbook wouldn't play any sound, I started going through forums and tried out some shell codes to make it work. Result – now there are no sound cards whatsoever in the Sound menu. Also next to the sound icon, there are three dashes instead of “waves” and I cannot control volume.

This is what it returns:

Code:

What do I do?

You probably removed or otherwise borked pulseaudio (because all of the low-level ALSA driver info looks okay). First thing I would do is purge puleaudio and reinstall it.

Code:

---

rm -rf ~/.pulse*
sudo apt-get purge pulseaudio
sudo apt-get install pulseudio

---

Then log out and back in. If that doesn't help, post pulse log: https://wiki.ubuntu.com/PulseAudio/Log
