The purpose-built crypto hardware and software is a bigger target for very high end attackers, but it is also almost certain to be designed to be harder to tamper with in the field

You cannot tamper with a sound card in the field to make it fail as a 
source of randomness, without making it into a very bad microphone 
input, with the result that it will get thrown out and replaced, so that 
the use can play games and make phone calls.
