<div class="moz-cite-prefix">Hi Andrew,<br>
<br>
Thanks for testing and confirming my observations.<br>
Yes, it's weird and, for now, nobody seems to know exactly what
could cause this problem and why DPS latency checker helps.<br>
<br>
I could understand this happening when you use a PC with limited
CPU power that runs out of free availably processing cycles.<br>
But it happens on a PC with lots of CPU power where I almost don't
see any CPU usage when I look at the CPU cores usage graphics.<br>
I also did try if there is maybe difference between W7 32 bit and
64 bit, but exactly same problem.<br>
<br>
And there is also still the problem with CTUNE that seems to
mesh-up my (frequency) database.<br>
<br>
But I will not make too much 'noise' about it, I know it's
'freeware' and I'm very happy with the overall performance.<br>
(I also run "a other very expensive SDR" that has much less
performance and more bug's...)<br>

have exactly the same problem with distortion as you

I can report that the distortions go away when I run DPC

what could be the difference when DPC is running??<br>

also have another distortion problem on the audio from
