Synopsis

mixer [+rec | -rec] devicename

Description

The mixer utility allows you to control audio input and output parameters:

choice of input and output channels
input and output volume levels
equalization (bass and treble) levels
stereo balance
channel mixing

It is used with audio playback and record programs, such as scosound(X1), vplay(1), and vrec(1).

An audio adapter must be configured on the system before mixer can be run.

Options

The +rec|-rec option adds or subtracts recording devices from a list of input sources. Multiple input devices can be selected but only one of each device type. Acceptable device names are: synth, line, mic, cd.

The remaining options control signal levels on the specified devices. The signal level value is represented as n:n, which indicates the relative value of left and right channels on a scale of 100. Entering mixer option with no value displays the current setting.
