Hi,

I'm trying to use the max9768,

I have defined it correctly in the dts file :

max9768: max9768@49 {
compatible = "max,max9768";
reg = <0x49>;
};

I can see that in the driver, i go in the function max9768_i2c_probe
<http://lxr.free-electrons.com/ident?v=4.1;i=max9768_i2c_probe> without
problem, and I don't see errors when executing this line :

 err <http://lxr.free-electrons.com/ident?v=4.1;i=err> =
snd_soc_register_codec
<http://lxr.free-electrons.com/ident?v=4.1;i=snd_soc_register_codec>(&client
<http://lxr.free-electrons.com/ident?v=4.1;i=client>->dev
<http://lxr.free-electrons.com/ident?v=4.1;i=dev>,
&max9768_codec_driver
<http://lxr.free-electrons.com/ident?v=4.1;i=max9768_codec_driver>,
NULL <http://lxr.free-electrons.com/ident?v=4.1;i=NULL>, 0);


I have put some log :

[    9.213797] ASoC: dai register 2-0049 #0
[    9.213806] ASoC: Registered codec 'max9768.2-0049'


my problem is that i don't know how to configure the volume ? Any idea ?
where is it ?

I don't see where is it in the amixer controls list :
