Hi Warren,

Cheap devices for 3 EUR (or $) will do most jobs very well. But it may 
be worth to spend some more money. 192 kHz sampling rate is available 
for a low price.
But you may first try to install a new driver for the existing one. Look 
for the name of the mother board and search in google for driver 
packages. Maybe it helps.
Or install Teamviewer software and let someone of "us" check if 
something can be done if you are not sure that everything is set 
correctly but doesn't work anyway...
It is likely that the internal one runs at 96 kS/s or maybe even 192. 
And the internal ones are often a bit better than the USB cards.

73, Stefan
