I load input samples to a circular buffer and pass them
to streming sound secondary buffer via notification
method (notification separated thread).

Deriving my code from streming data Microsoft example, I
can listen quite good sound form audio card from input
signal at 4096 or 8192 sample rate.

For my scope I'm using a stay on top form, but when I
change focus to other application or move form I have
this 2 problem:

1) Play Notification events lost constancy in timing
versus input samples flow stays constant.

2) a strange noise is random introduced in audio, mixed
to my audio signal. How can I understand if this is
caused from kmixer mixing disturb from other aplications
audio, or strange interaction in my load input sample
function.

Thanks

Regard
Francesco
