[Elecraft] KX3 -Win4K3 Suite - external Soundcard

[Kev Schache]

Greetings from South Australia to all,

I'm an octogenarian ham, first licensed in 1960,  the very proud owner- 
builder of a K2 and more recently a KX3, extremely happy with Elecraft 
and both radios..

I'm looking at the Win4K3 Suite with a view to using it with the KX3 and 
my Windows 10 Notebook to get some form of pan-adapter, the PX3 being 
out of my reach financially. I note that I need an external USB stereo 
sound card to achieve the correct connection. I've been considering the 
ASUS Xonar U5 as a possible sound card but I'm uncertain if it will work 
with Windows 10. Hence my questions.

Has anyone successfully used the ASUS Xonar U5 USB external sound card 
with Windows 10 / Win4K3 Suite?

Alternatively, is there some other recommended external USB sound card 
for use with the Win4K3 Suite and Windows 10?

Thanks to all,

73,
