You can't force the driver to detect your soundcard if the driver
doesn't detect it :-)

If you have a supported sound card and are loading the correct driver,
then the device will be probed when you load the driver (at boot,
after boot, whenever), and the device node will be created at that
time if the probe is successful.

You should, yes.
