Recording Sound

Ubuntu provides a number of tools that enable you to control volume, mix, and other sound recording functions. The Kmix sound mixer (available when you install the KDE window manager or Kubuntu) acts as a virtual mixing board, taking sound inputs from different sources, enabling you to adjust their individual volumes, mute them, and listen to them through your sound card.

If you need to control sound from command line, use the alsamixer command as seen in Figure 10.6, which can be used to adjust balance or volume in text mode using the left and right cursor keys to select a channel and the up and down keys to adjust the volume.
