I have a custom i.MX6S board with a SGTL5000 Audio-Codec.
The codec is connected to a speaker (via amp) and a headphone jack. It runs with Linux 4.5.
It works very nice and all, but now I want to manually mute the Line-Out. I don't want to control the volume, just mute it.
Is there a simple way to set this bit via I2C?
Or do I have to implement this somehow in the driver?
