DESCRIPTION
XMixer
is used to control your soundcard volume settings. It runs with Linux
sound drivers V2.0 and above.
This document describes all the features of
XMixer.
Your soundcard may or may not support everything of it, please read be
sure to read your hardware manual.
USAGE
The program has several sliders to control the volume of your supported sound
hardware. In addition, you have a 'loudness', a 'stereo wide' and a 'mute'
button above the sliders. Below the sliders are buttons to select the
recording source.
Options offered by
XMixer
are the following:
-display lt;displaygt;
Show the control window on the given display.
-fn lt;fontgt;
Use this font rather than the default. The given font should be fixed width
and about the same size like the default font. If not, the window will look
ugly.
-1
This is the same as
-all
and is available for historical reasons.
-all
Big mixer mode. Show all sliders supported by the driver. (You may enable
each slider separately with X-Resources, this switch overrides it. See below.)
-debug
Enable debugging output. Will show which sliders are enabled and which of
them are actually supported by the driver.
-device lt;devicegt;
Use the given device. Default is /dev/mixer.
-poll
Poll the mixer device three times a second and update the sliders. If you use
this, changes to the settings made by other programms will show up on your
mixer window. Though this causes only a minimal system load, it keeps the
process in memory, so don't use this if you have a slow system or not
much memory.
-nopoll
Don't poll the mixer. Wether -p or -np is the default depends on the *pollMixer
X11
resource.
-rate lt;\µsecgt;
If polling is enabled, this will set the delay between each poll in
microseconds. Values below 10000 are silly and are rejected.
-v
Print current version and exit.
RESOURCES
XMixer
understands a large number of
X11
resources which are listed below. These system wide resources usually sit in
a file called
/usr/lib/X11/app-defaults/XMixer.
Personal resources reside either in
~/.Xdefaults
or
~/.Xresources
depending on your installation. To put an
XMixer
resource into your personal resource file, prefix it with the word
xmixer.
After editing your personal file, be sure to run
xrdb ~/.Xresources
or
xrdb ~/.Xdefaults
to make them work. There is no need for a prefix or an invocation of
xrdb
if you change the system wide file.
STANDARD RESOURCES
SPECIAL RESOURCES
Special
XMixer
resources are:
*brightBorder: gray94
*darkBorder: gray40
*hilightColor: gray72
These settings are responsible for the 3D-look-and-feel of the program.
Just play with the values to see what they do.
*mixerDevice: /dev/mixer
Use the given device. Default is /dev/mixer.
*pollMixer: off
Please see description of
-poll
or
-nopoll
commandline option above.
mixerMode:
This resouce is no longer supported.
The following resources are used to enable or disable each slider separately:
vol:
Enables or disables master volume control.
bass:
Enables or disables low frequency control.
treble:
Enables or disables high frequency control.
synth:
Enables or disables FM Synthesizer control (e.g. OPL2/OPL3/OPL4 or WaveTable
aka /dev/sequencer).
pcm:
Enables or disables digital audio control (aka /dev/dsp and /dev/audio).
speaker:
Enables or disables PC-speaker emulation control.
line:
Enables or disables line input control.
mic:
Enables or disables microphone input control.
cd:
Enables or disables internal cd playback control.
mix:
Enables or disables monitor volume control.
pcm2:
Enables or disables soundblaster emulation control (aka /dev/dsp2).
rec:
Enables or disables recording level control.
igain:
Enables or disables input gain level control.
ogain:
Enables or disables output gain level control.
line1:
Enables or disables line input 1 control.
line2:
Enables or disables line input 2 control.
line3:
Enables or disables line input 3 control.
Each of the above resources enables or disables its slider. The names are
taken from the current VoxWare include file. (Version 3.5.2 as of this
writing.)
Not all of these resources may be supported by your hardware.
XMixer
checks for each requested slider whether it is really supported. If a slider
is not supported, it will be silently disabled. Use the
-debug -all
switches to check what is supported if in doubt.
If none of the above resources are set, they default to on. If at least one
resource is present, the other resources default to off.
TROUBLESHOOTING
Q:
It quits with 'xmixer: Can't open /dev/mixer: No such file or directory'
A:
You can use this program only if you have a soundcard. Check if the
file exists. If not, check the sound-faq on how to create the device entry.
Q:
It quits with 'xmixer: Can't open /dev/mixer: No such device or address'
A:
You probably don't have sound support in the kernel. Check if your
sounddriver is installed properly and if it has mixer support. Try
cat /dev/sndstat
and see if it prints something like
1 mixer(s) installed.
If you get an error message instead, please check the sound faq.
Q:
I don't have the default font, so the program always tells me an annoying
message that it uses a fixed font, how can i get rid of this?
A:
Call it as 'xmixer -fn fixed' or change the font in the default file.
The default file is usually /usr/lib/X11/app-defaults/XMixer.
Q:
Some buttons appear stippled gray and can't be used.
A:
This is not a bug. Your sound driver or your sound hardware simply does not
support the feature this button is controlling, so the button is disabled.
Q:
Some buttons don't work. E.g., if I press the mute button, it immediately
pops out again and nothing happens.
A:
Some sounddrivers are known to have bugs. The PAS driver in Kernel 1.1.8
for example lacks the support for muting and stereowide. It simply ignores
any try to set those values.
BUGS
Some sound drivers are known not to support all possible settings. So if
nothing happens if you press a button or move a slider, this may be due to
lack of hardware support or due to a driver bug.
