There are some good, inexpensive external ADC boxes such as from ADS 
Tech, to say nothing of the more elaborate ones from Creative. They are 
easy enough to interface to permit borrowing a unit just to find out 
whether that would solve your problem.

There are several different potential causes which can be analyzed from 
the sound produced. For example, if the buzz is uniform in both loud and 
quiet passages, spectral analysis will usually identify the culprit in 
the electrickery; if it varies with the audio signal, the cause may be 
in the sound card. Unfortunately, I've had faulty 'cards' which were 
built into the motherboard and could not be killed; in one case, I sold 
the computer to start over from a decent starting point.
