no sound in ubuntu

cat: /proc/asound/cards: No such file or directory


it was working an hour ago and not the sound has gone off and the system says sound card not found??


Open Terminal console to get to the command-line. This should launch the gnome-terminal application.

In gnome-terminal, click on Edit::Profiles::Edit "Default" profile::Scrolling::Choose "Unlimited" as scrolling option::Close::Close.

So make sure that unlimited scrolling is ENABLED in gnome-terminal. Or else it will not be possible to send us the full output from step 3.

Step 3

Please make sure you have rebooted your computer at least once. Then proceed with running the following 2 commands - copy&paste (with the mouse) each command onto the Terminal and then hit after each command.

Tip: If you have a wheel mouse or 3 button mouse, you do not need to type commands into the Terminal. Highlight the command written on the webpage. Move your cursor anywhere in the Terminal and press the wheel or middle button. Automatic Copy and paste! No spelling mistakes! No Typos! No other errors!
