[hpsdr] Audio distortions during zoom/pan panadapter display_2

[H.A.Meijer]

Warren,

thanks for replay,


The windows 7 is a completely fresh install, not much other software 
then powersdr that
could interference.
I also have been playing around a bit at the bios-setup, that has all 
kinds of setting for the cpu.
I did slowdown the cpu by lowering the 'cpu ratio setting', also 
lowering the numbers of cpu cores.
Enabling/disabling: Throttling, HT setting, speedstep, c-state etc. 
whatever they mean,
but no change.

For now I'm pretty much running out of possible things to try.
I guess my system is like good wine, that has to age a bit.

thanks
73 Bert
