Try to increase the number of virtual channels, e.g. "sysctl

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

Try to mute the device and then unmute it again (at least the GNOME
panel applet is able to mute/unmute a device, and I have to do the same
in Windows too when I want to use my uaudio device).

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.
