I can see that the USB devices connected have changed btween the working
case and non-working audio case.
This is for the following device which I believe is the QDX:

Product ID : 0xA34C
Andy,
Yes, Attached another two checks. This on a W7 netbook. Although they are two different QDXs the fault looks the same.
I now have two QDX they both have the same problem.
After the first boot they will not boot properly again until some time has elapsed, maybe 1/2 hour.
So far I have tried 3 computers, 4 power sources. Widows 7 and 10.
Seems the QDX is the only common item.
I note another who is finding this 100% noise problem
/g/QRPLabs/message/74801This one here
/g/QRPLabs/message/74804 has a similar problem that sounds like the way mine started. Mine has got worse and now takes much longer before I get a good startup.
The high noise situation after startup is now more common, previously a partially working state was observed where the self test traces were defective.
Greg has two USBTree files but the differences are fewer.
You mention logging. Do you mean the QDX log? This can only be enabled after startup, I can try but it will not log anything until after the startup fault has occurred.
I can look at Windows Event Viewer to see if anything is shown.
Thanks for your interest.
