There still seems something wrong with your package management system preventing that the sound drivers get installed.

Please provide the output of the following three commands (make sure each of them is pasted as one line):

find /etc/apt -name '*.list' -exec bash -c 'echo -e "\n$1\n"; cat -n "$1"' _ '{}' \;
sudo apt-get update
sudo apt-get upgrade

and copy/paste the output as done before

FIrst output
find /etc/apt -name '*.list' -exec bash -c 'echo -e "\n$1\n"; cat -n "$1"' _ '{}' \;

/etc/apt/sources.list

Second Output
dumisani@dumisani-HP-Compaq-6735s:~$ sudo apt-get update

Third Output
sudo apt-get upgrade

It seems that you lost the contents of your sources.list configuration file.

Please look in your /etc/apt directory if there is a backup of the file (something like sources.list.bck or sources.bck).

If there si a healthy backup copy you might try replacing the empty file with the backup with a command like
sudo cp /etc/apt/sources.list.bck /ect/apt/sources.list

Or you also can create a new file from scratch by doing the following:

open a terminal and issue the command

gksudo gedit /etc/apt/sources.list

Paste the following contents into the editor window that opens:
