[hpsdr] Audio distortions during zoom/pan panadapter display

[H.A.Meijer]

Hi,

Just made a observation that can stop the audio-distortions when when 
zooming/pan
the pan adapter.

To test the possibility of latency spike's, I just downloaded the 'DPC 
Latency Checker 1.4' from:
http://www.thesycon.de/deu/latency_check.shtml

When starting the program there are no audio distortion anymore!
Closing the program brings back the audio distortions!

Hans, Sie könnten das vielleicht auch mal versuchen.
