The sample configs really eed work.  Having said that, the ices-live.xml
should show you how to do this.  You could of course get the hardware to
capture at 11khz, assuming it can (most can). But if not, try something
like this:


            <!-- stereo->mono downmixing, enabled by setting this to 1 -->


That's taken from a config I use, so obviously change it for your needs.
Actually, 22khz at quality -1 will probably fit your bandwidth
requirements, but if you want to go with 11khz, I'd suggest using a higher
quality value than -1.  Experiment and see what you end up with.
