HowdyComputers deal with synchronizing multiple clocks all of the time. But they don't deal with real-time data much at all. Your computer intuition isn't that reliable when talking audio...
As I stated tho S/PDIF isn't perfect, neither is USB (for audio) nor AES/EBU.
It isn't wild guessing of the clock, the guessing is controlled with standard control theory, the same theory needed to seek on a hard disk and then again to read it's data. It's just that in that case, if you miss you can try again... With audio you just optimize for a different goal.
As I mentioned if the DAC is the clock source things can get a lot simpler (at least jitter wise) but on consumer gear this isn't supported very often.
