[hpsdr] Audio distortions during zoom/pan panadapter display_2

[H.A.Meijer]

Hi Hans,

Thanks for confirmation and yes no need to 'run' the checker, just 
starting is enough.
Maybe some setting is enabled when running that program, i don't know.
In the meanwhile I also test with some different video drivers from 
nvidia and also
all other video settings are "default"  but so far no results.

Here is where my knowledge ends, maybe a "windows code writer" can help.
