Actually it is both ;-) Modprobe accepts either filename for its
configuration data.

While this trick still works, newer versions of modprobe officially
support hooks for installing/removing modules. The manual page lists
these commands:

keep
parameter=value
options module symbol=value ...
alias module real_name
pre-install module command ...
install module command ...
post-install module command ...
pre-remove module command ...
remove module command ...
post-remove module command ...

For the purpose of configuring the sound subsystem, the post-install
hook will have to be set.

P.S.: Who maintains the Sound HOWTO? This information should probably
be updated.
