I missed the start of this thread but it you need it many computer audio interfaces can be run off an external clock. It is really common to do this in a studio setup.
You think "does it matter? Can humans hear a 10ppm difference in pitch?" No but if you make two recordings each using a different clock then the error is cumulative and you might get a phase error near the end. So most audio interface have a clock input. Even my cheap $200 Presonus unit will take a clock input via it's fiber optic s/pdiff input. I still doubt it matters much for normal recording studio work.
