I'm running Ubuntu 12.04 Gnome classic. Obviously playing the music shows there is a sound card present. But I've read that there might be multiple sound cards present on a single system.

How can I know how many sound cards are present on my system? Also, how can I know which all they are?

To detect your soundcard, use sudo aplay -l from the Terminal.

Type in a terminal:

 hwinfo | grep sound.card_id

hwinfo is not avaiable in the default Ubuntu installation. It has to be manually installed by using sudo apt-get install hwinfo – saji89 May 24 '12 at 17:16
