<H3><A NAME="ss4.1">4.1 Mixer layout and stored Profiles</A>
</H3>

<P>
<P>This is one of the advanced features of kmix. If you have a standard
layout you like, you can save this layout. A layout stores for each
channel four configuration options.
<P>
<P>
<UL>
<LI> The volume of the channel</LI>
<LI> If the channel is shown</LI>
<LI> If the channels slider is split (for stereo channels)</LI>
<LI> If the channel are muted.</LI>
</UL>
<P>If you want to save the current layout, just press <CODE>Control-1</CODE>
to save the layout as profile <CODE>1</CODE>.
Likewise you can save profile <CODE>2</CODE>, <CODE>3</CODE> and <CODE>4</CODE> by pressing
<CODE>Control-2</CODE>, <CODE>Control-3</CODE> or <CODE>Control-4</CODE>.
<P>You can restore a profile by pressing <CODE>1</CODE>, <CODE>2</CODE>, <CODE>3</CODE> and
<CODE>4</CODE> respectively. If you want to start kmix with a certain
layout directly set up, you must pass a command line argument.
<P>
<H3><A NAME="ss4.2">4.2 Command line arguments</A>
</H3>

<P>
<P>You can pass some parameters to kmix, to have influence on
kmix's initial settings.
<P>
<P>
<P>
<UL>
<LI> <CODE>-r</CODE> will restore the default set (set 1), that you saved
by pressing<CODE>Control-1</CODE>.</LI>
<LI> <CODE>-R n</CODE> will restore the given set.</LI>
<LI> With passing <CODE>-devnum n</CODE>, kmix will use the n'th mixer
device on your system.</LI>
</UL>
<P>
<P>
<P>
<H3><A NAME="ss4.3">4.3 Multiple Soundcards</A>
</H3>

<P>
<P>KMix is prepared for multiple sound cards. If called via the KDE Panel,
the default mixer is used. For the Open Sound System, this is
<CODE>/dev/mixer</CODE>. For other operating systems or sound drivers,
this may vary.
<P>If you want KMix to use a specific soundcard (primary, secondary, ...),
you must tell this KMix on startup.
You can start the mixer with a device number, using the <CODE>-devnum n</CODE>
parameter. <CODE>-devnum 0</CODE> means the default
device, 1 your primary mixer, 2 your secondary mixer and so on. If
you use this regulary, you should create a new program kdelnk (using kfm
or the menu editor). This should just call kmix with the appropriate
device number as parameter, for example "kmix -devnum 2".
