PulseAudio Volume Conrtrol

PulseAudio Volume Control is a proxy go-between for the hardware and the underlying kernel sound component that provides device drivers for sound cards; ALSA (Advanced Linux Sound Architecture). PulseAudio was added to ensure compatibility with the widest array of hardware (and software). PulseAudio is the easiest way for most users to control the volume on their computers.

PulseAudio Volume Control

But, if you need access ALSA; go to
Menu --> System Tools --> LXTerminal
Type: alsamixer[Enter] or [return]

Move to each sound control in Alsamixer with the left and right arrow keys;the selected device will show red. There are usually too many devices to show in one window; keep hitting the right arrow key the first time through to see them all. As of ALSA 1.0.6 there are three different views: Playback [F3], Capture [F4] and All [Enter]. Adjust volume with the up and down arrow keys. "00" means no volume, "MM" means mute. Toggle mute/unmute with the [M] key. Exit, and return to LXTerminal by hitting the [ESC/esc] key.
