I have tried some of these cheap units from eBay. Too cheap is right. They
may seem to work on PSK31 and they are fine for audio but I doubt if weak
signal copy of digimodes is very good. I tried using one for packet and even
though the signal looked OK on the waterfall I never decoded a single
packet. I don't know what the bit resolution or sample rate they use but I
suspect the drivers do a crude resampling between the parameters the
software selects and the ones the device actually runs at and a lot of
information gets lost in the process.

What you can do, though, is reconfigure windows so the cheapie USB adapter
is the default for computer audio, which frees up the on board sound card
for digital radio use. Despite comments in various places to the contrary,
I've always found the built-in audio chips to work pretty well for digital
modes.
