I would prefer something which is comfortable for user. The module 
parameter or sysfs file is not a good way to explain users how they can 
change the beep behaviour.

We have basically four ways:

1) module parameter (difficult tracking of changes through sysfs)
2) sysfs file
3) current implementation
4) create new control with different name (like "HDA Beep Enable Switch")
