NAME

6       snd_ctl_add_slave - Add a virtual slave control
7

SYNOPSIS

9       int snd_ctl_add_slave(struct snd_kcontrol * master,
10                             struct snd_kcontrol * slave);
11

ARGUMENTS

13       master
14           vmaster element
15
16       slave
17           slave element to add
18

DESCRIPTION

20       Add a virtual slave control to the given master element created via
21       snd_ctl_create_virtual_master beforehand. Returns zero if successful or
22       a negative error code.
23
24       All slaves must be the same type (returning the same information via
25       info callback). The fucntion doesn't check it, so it's your
26       responsibility.
27
28       Also, some additional limitations: at most two channels, logarithmic
29       volume control (dB level) thus no linear volume, master can only
30       attenuate the volume without gain
