Sub-query as function argument

Is it possible to execute a SELECT query as an argument to a function?

Example:

SELECT my_func('Sample', NULL, SELECT MIN(year) FROM audio);

In my particular case, my_func inserts columns into another table; I wish to
use values from another table as the arguments. The interior SELECT will
return only a single value; perhaps it needs to be wrapped in another
function?

TIA.
Mike.
