[alsa-devel] Reset to clean state after snd_ctl_add_integer_elem_set ?

I'm using snd_ctl_add_boolean_elem_set and snd_ctl_add_integer_elem_set to create some user kernel controls. While the operation work find I did not find any simple command to erase all those controls.

Even "/usr/sbin/alsactl --init" does not remove those added controls. The only way I find is to prevent /usr/sbin/alsactlto happen during reboot to really reset the ALSA driver to an initial state, which is really not pratical when developing/debugging.

Question: is there a simple method to return to a clean and fresh state after snd_ctl_add_xxxx without rebooting the machine ?

Thank you
