The list 72of mixer devices that may be modified are: 73.Pp 74.Bd -ragged -offset indent 75vol, bass, treble, synth, pcm, speaker, mic, cd, mix, 76pcm2, rec, igain, ogain, line1, line2, and line3. 77.Ed 78.Pp 79Not all mixer devices are available. 80.Pp 81Without any arguments, 82.Nm 83displays the current settings for all supported devices, followed by information 84about the current recording input devices. 85If the 86.Ar dev 87argument is specified, 88.Nm 89displays only the value for that 90.Ar dev . 91.Pp 92To modify the mixer value 93.Ar dev , 94the optional left and right channel settings of 95.Ar lvol Ns Op : Ns Ar rvol 96may be specified. The 97.Ar lvol 98and 99.Ar rvol 100arguments may be from 0 - 100. Omitting 101.Ar dev 102and including only the channel settings will change the main volume level. 103.Pp 104If the left or right channel settings are prefixed with 105.Cm + 106or 107.Cm - , 108the value following will be used as a relative adjustment, modifying the 109current settings by the amount specified. 110.Pp 111If the 112.Fl s 113flag is used, the current mixer values will be displayed in a format suitable 114for use as the command-line arguments to a future invocation of 115.Nm 116(as above). 117.Pp 118To change the recording device you use one of: 119.Bl -tag -width =rec -offset indent 120.It Cm ^rec 121toggles 122.Ar rdev 123of possible recording devices 124.It Cm +rec 125adds 126.Ar rdev 127to possible recording devices 128.It Cm -rec 129removes 130.Ar rdev 131from possible recording devices 132.It Cm =rec 133sets the recording device to 134.Ar rdev 135.El 136.Pp 137The above commands work on an internal mask.
