What I found is, small USB audio dongles don't process low frequencies well because they use too small capacitors. This can be improved by DIY soldering. Also some of them do a bad job in noise shaping, leaving quantization noise in audible range. That is something you can't improve. Here is a page describing some of my findings:

Maybe it's time to design our own audio dongle.
