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
Fulup
