-.SH NAME
-amixer \- command-line mixer for ALSA soundcard driver
-.SH SYNOPSIS
-\fBamixer\fP [\fI\-option\fP] [\fIcmd\fP]
-.SH DESCRIPTION
-\fBamixer\fP allows command-line control of the mixer for the ALSA
-soundcard driver.
-\fBamixer\fP supports multiple soundcards.
-
-\fBamixer\fR with no arguments will display the current mixer settings
-for the default soundcard and device. This is a good way to see a list
-of the simple mixer controls you can use.
-
-.SH COMMANDS
-
-.TP
-\fIhelp\fP
-Shows syntax.
-
-.TP
-\fIinfo\fP
-Shows the information about a mixer device.
-
-.TP
-\fIscontrols\fP
-Shows a complete list of simple mixer controls.
-
-.TP
-\fIscontents\fP
-Shows a complete list of simple mixer controls with their contents.
-
-.TP
-\fIset\fP or \fIsset\fP <\fISCONTROL\fP> <\fIPARAMETER\fP> ...
-Sets the simple mixer control contents. The parameter can be the volume
-either as a percentage from 0% to 100% with \fI%\fP suffix,
-a dB gain with \fIdB\fP suffix (like -12.5dB), or an exact hardware value.
-The dB gain can be used only for the mixer elements with available
-dB information.
-When plus(+) or minus(\-) letter is appended after
-volume value, the volume is incremented or decremented from the current
-value, respectively.
-
-The parameters \fIcap, nocap, mute, unmute, toggle\fP are used to
-change capture (recording) and muting for the group specified.
-
-The optional modifiers can be put as extra parameters to specify
-the stream direction or channels to apply.
-The modifiers \fIplayback\fP and \fIcapture\fP specify the stream,
-and the modifiers \fIfront, rear, center, woofer\fP are used to specify
-channels to be changed.
-
-A simple mixer control must be specified. Only one device can be controlled
-at a time.
-
-.TP
-\fIget\fP or \fIsget\fP <\fISCONTROL\fP>
-Shows the simple mixer control contents.
-
-A simple mixer control must be specified. Only one device can be controlled
-at a time.
-
-.TP
-\fIcontrols\fP
-Shows a complete list of card controls.
-
-.TP
-\fIcontents\fP
-Shows a complete list of card controls with their contents.
-
-.TP
-\fIcset\fP <\fICONTROL\fP> <\fIPARAMETER\fP> ...
-Sets the card control contents. The identifier has these components: iface,
-name, index, device, subdevice, numid. The next argument specifies the value
-of control.
-
-.TP
-\fIcget\fP <\fICONTROL\fP>
-Shows the card control contents. The identifier has same syntax as for
-the \fIcset\fP command.
-
-.SH OPTIONS
-
-.TP
-\fI\-c\fP card
-
-Select the card number to control. The device name created from this
-parameter has syntax 'hw:N' where N is specified card number.
-
-.TP
-\fI\-D\fP device
-
-Select the device name to control. The default control name is 'default'.
-
-.TP
-\fI\-s\fP | \fI\-\-stdin\fP
-
-Read from stdin and execute the command on each line sequentially.
-When this option is given, the command in command-line arguments is ignored.
-
-Only sset and cset are accepted. Other commands are ignored.
-The commands to unmatched ids are ignored without errors too.
-
-.TP
-\fI\-h\fP
-Help: show syntax.
-.TP
-\fI\-q\fP
-Quiet mode. Do not show results of changes.
-
-.SH EXAMPLES
-
-.TP
-\fBamixer \-c 1 sset Line,0 80%,40% unmute cap\fR
-will set the second soundcard's left line input volume to 80% and
-right line input to 40%, unmute it, and select it as a source for
-capture (recording).\fR
-
-.TP
-\fBamixer \-c 1 \-\- sset Master playback -20dB\fR
-will set the master volume of the second card to -20dB. If the master
-has multiple channels, all channels are set to the same value.
-
-.TP
-\fBamixer \-c 1 set PCM 2dB+\fR
-will increase the PCM volume of the second card with 2dB. When both
-playback and capture volumes exist, this is applied to both volumes.
-
-.TP
-\fBamixer \-c 2 cset iface=MIXER,name='Line Playback Volume",index=1 40%\fR
-will set the third soundcard's second line playback volume(s) to 40%
-
-.TP
-\fBamixer \-c 2 cset numid=34 40%\fR
-will set the 34th soundcard element to 40%
-
-.SH BUGS
-None known.
