The Delta44 driver for 32 bit WinXP can be installed under the
32 bit version of Win10 by running the installer in XP compatility
mode. It works properly sometimes. Below is part of my posting on the
Linrad mailing list May 31 2017:

The "B" problem may also be caused by soundcard errors. As far as
I know, the only reliable driver for the Delta44 is the Win XP 32 bit
driver. It is fine under Win XP 32 bit, and once I was running it
sucessfully under 32-bit Windows 10 installed in compatibility mode.
(I have not been able to reproduce that.) All other combinations
of Windows versions and Delta44 drivers cause glitches and surely
they constitute errors that may degrade detection. There are many
other soundcards than the Delta 44. Dynamic range would be a bit lower
for the visible range (±45 kHz) but the wide range dynamic range would
not be affected.

All of this JT65 vs Q65 discussion raised a question...seems like the Delta
44 is the preferred sound card but win 10 compatibility is an issue.
I'm wondering if anyone has done any testing on external audio interfaces
(USB interconnect) and what have you found to be the best for EME use
particularly JT65B. I do not use MAP 65 so just the SSB bandwidth is all I
