Specifies a channel map. If your audio device has more than two
outputs this allows you to route audio to auxillary outputs. For
predictable results you should also specify a "format" with a fixed
number of channels, e.g. "*:*:2". The number of items in the channel
map must match the number of output channels of your output device.
Each list entry specifies the source for that output channel; use "-1"
to silence an output. For example, if you have a four-channel output
device and you wish to send stereo sound (format "*:*:2") to outputs 3
and 4 while leaving outputs 1 and 2 silent then set the channel map to
"-1,-1,0,1". In this example '0' and '1' denote the left and right
channel respectively.
</para>
<para>
The channel map may not refer to outputs that do not exist according
to the format. If the format is "*:*:1" (mono) and you have a
four-channel sound card then "-1,-1,0,0" (dual mono output on the
second pair of sound card outputs) is a valid channel map but
"-1,-1,0,1" is not because the second channel ('1') does not exist
when the output is mono.
