I have a little bit strange Desktop. It is a HP Compaq desktop with all its components enclosed by the factory(like a laptop). I don't know what the audio and video devices are but on Windows I just put the GIGABYTE definition CD and it does all the work for me.

Now, how can I do such a thing on Ubuntu 11 ?!

The only thing I miss on Ubuntu is audio. I can't play any music or video !!

A thing I think it will be useful is that before I install Ubuntu and erase Windows, the Audio device or something like that was "Realtek Sound Effec Manager". I copied the name.

How can I play audio on my PC ?!

Take a look at the output of lspci. –  mikewhatever Jun 29 '12 at 20:06
    
Two things, try a search here for 'Realtek' to see what issues you might be facing, and download a newer version of Ubuntu. 12.04 is the current version and it's the best choice unless you have a specific reason for not using it. –  Tom Brossman Jun 29 '12 at 20:12

1 Answer 1

I think you are using Realtek sound card. Type in a terminal

lspci

It will show you your sound card and other devices attached with your computer.

To install Realtek driver you can download the package from their website.

Click to download

Extract it and click install. Then reboot your system.

This is the audio device I seem o have "Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 01)" What should I do ?! –  Osama Jun 29 '12 at 21:36
    
You can do two things. 1) Install Ubuntu 12.04 LTS or 2) Try to installing realtek driver. Installing this driver will be ok. I have HP Compaq CQ42 with realtek. But 'lspci' show exect thing. But i install latest driver of realtek. Try to install this driver 1st. If it don't work install Ubuntu 12.04 LTS. It will fix most of your driver problem. –  ScareCrow Jun 29 '12 at 22:33
