OK, first of all: The gnome-alsamixer is just a piece of software to make controlling the sound output more easily - it's not the driver or anything. And yes, the soundcard is a chip, so you can't delete it.
Then, the apt-get commands were wrong - use
- sudo apt-get remove gnome-alsamixer
to remove and
- sudo apt-get install gnome-alsamixer
to install it.
Now, for your installation issues, you might want to start using synaptic instead of apt-get - it's easier to use for the moment as it uses a graphical interface and so you don't have to worry about syntactical problems.
Next, we have to track your problem. My guess is, that for some reason,
alsa isn't set up correctly. Try using
alsamixer to see, if any card is recognised. The alsamixer is a mixer, which lets you control the various sound levels. You can navigate with the arrow buttons, the tab button and quit it with the
Esc button.
If that works, you possibly just have to set some of the levels up. If it doesn't, please tell us the output of the command.
Also, the command
might give you some more information. Otherwise, try
. In any case, post the results here please.
