Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I have just installed the latest version and I have no sound. I tried all solutions I could find on the web, including drivers from the sound dev repository, running alsamixer, etc, but nothing helps. Would someone please help? I am new to ubuntu, I have no idea where to look. Microphone works, and it seems to recognize my laptop's on-board sound.

more info on your sound card, laptop and desktop environment (Unity, KDE, Xfce) needed –  cipricus Aug 27 '12 at 12:14
    
please tell me what commands I need to run and I will post the output –  akonsu Aug 27 '12 at 12:16
    
sudo lshw | less and specify the Desktop Environment too –  cipricus Aug 27 '12 at 12:19
    
I have edited my question. thanks! what is the Desktop Environment? (yes I know the question sounds stupid) although I think it is unity. whatever comes with the OS by default. –  akonsu Aug 27 '12 at 12:26
    
it is not stupid: every ubuntu user will bump into the issue: there are more ubuntus that one usually knows when starting using ubuntu. after founding that i put the lesson on this blog: cipricuslinux.blogspot.com/p/… just for my own use, please excuse the self-promoting aspect. in fact the answer to a question like yours might be different according to the DE you have –  cipricus Aug 27 '12 at 12:38

To answer my own question: for me upgrading my laptop's (Toshiba Satellite with Conexant audio) BIOS helped. For more information on how to update BIOS under Ubuntu, take a look at HOWTO: Flash BIOS, The Ubuntu Way

In the "Sound settings" Dialogue be sure you have selected "Analog Output (Built in Audio)" instead of anything else.

Install "gnome alsa mixer" and "pulse audio control" and set the values to max.

In the "Sound settings" Dialogue be sure you have selected "Analog Output (Built in Audio)" instead of anything else.__ copied from your answer. For my case I only have Dummy output and nothing else _ no testing sound / no input and everything silence but the videos is perfect.
