I am using Kali Linux 2.0 Debian 64 bit and I was having some problems with Sound output, I went to a certain website which advised me to execute the following    sudo killall pulseaudio sudo apt-get purge pulseaudio pulseaudio-utils gstreamer0.10-pulseaudio     paman pavumeter pavucontrolrm ~/ .pulse-cookie  rm -r ~/ .pulse sudo apt-get install alsa-base alsa-tools alsa-tools-gui alsa-utils  alsa-oss alsamixergui libalsaplayer0apt-get install kmix restartapt-get install pulseaudio and hit enter and and last type apt-get install gnome-core and again hit enter.reboot And the next thing I see all my bookmarks and files on my hard drive are missing.  Is there anyway I can retrieve them?
All my files have been erased after I tried to make my audio better
