It matters if it's really bad. But given today's digital components and
technology an audio card designer really has to be quite incompetent
(or have an incompetent manager) in order to get to that point.
For my work I design systems that sample at up to 1 Ghz. Clock jitter
in sampled signals results in 'phase noise' and there are usually
quite heavy specs on that in space telecom equipment. But even with
sample periods in the nanosecond range it's usually *not* the AD or
DA converters that dominate the phase noise equation.
