Changed to 4 and changed the hw.snd.pcm0.vchans to 4 and a readout of 
"sysctl hw.snd" follows;
hw.snd.targetirqrate: 32
hw.snd.report_soft_formats: 1
hw.snd.feeder_rate_ratemin: 4000
hw.snd.feeder_rate_ratemax: 1102500
hw.snd.feeder_rate_scaling: 5
hw.snd.feeder_rate_buffersize: 8192
hw.snd.verbose: 1
hw.snd.unit: 0
hw.snd.maxautovchans: 4
hw.snd.pcm0.buffersize: 16384
hw.snd.pcm0.vchans: 4
hw.snd.pcm0.vchanrate: 48000

How would I mute/unmute devices by using a widget in KDE or do you suggest 
changing to gnome, or is there a command line like "mixer pcm 0" or is the 
"push to mute" volume switch used.

I had near success when I heard window like noises when I was playing with 
settings in KDE control centre but they went dead again and have been trying 
to recreate the settings but to no avail.  Also is there any way of running 
at it Hi-speed becasue at the minute it's running at Full speed (12MB/s).

Thank you for helping me.

Bye,
Christopher
