[alsa-devel] ASoC: Machine Driver Interaction with Codec Drivers

[Lars-Peter Clausen]

Hi,

No this is currently not really supported. There were some ideas for this a
long long time ago, but it never got implemented. And today basically
everybody takes care of hiding the controls from userspace.

That does not mean it does not make sense to have such a feature, but it
needs somebody with a motivation to implement it.

For example, our hardware doesn’t wire the IN2_L and IN2_R pins to anywhere, so the codec controls that determine their connections into the input mixer do nothing on our hardware and I’d like to hide them from the user in the mixer.
