SND_CTL_ADD_SLAVE_UN(9)	       Control/Mixer API       SND_CTL_ADD_SLAVE_UN(9)

NAME
       snd_ctl_add_slave_uncached - Add a virtual slave control

SYNOPSIS
       int snd_ctl_add_slave_uncached(struct snd_kcontrol * master,
				      struct snd_kcontrol * slave);

ARGUMENTS
       master
	   vmaster element

       slave
	   slave element to add

DESCRIPTION
       Add a virtual slave control to the given master. Unlike
       snd_ctl_add_slave, the element added via this function is supposed to
       have volatile values, and get callback is called at each time quried
       from the master.

       When the control peeks the hardware values directly and the value can
       be changed by other means than the put callback of the element, this
       function should be used to keep the value always up-to-date.
