[alsa-devel] [PATCH v2] ASoC: wm8960: add dapm kcontrols to select left/right ADC input source
Add dapm kcontrols to select left/right ADC input source, one to select the left ADC input source and one for the right ADC input source.
In default, the left ADC will select the left input, and the right ADC will select the right input. When the left(right) ADC select the right(left) input, the left(right) input path will be powered down.

Are you sure this is correct? My reading is that those bits don't affect routing at all, they mearly determine how the channel is sent out on the AIF.
Thanks, Charles

Are you sure this is correct? My reading is that those bits don't affect routing at all, they mearly determine how the channel is sent out on the AIF.
I have tested on my board, it can works, but it has something wrong.
If set "ADCR Source" to "Left", RINPUT1(RINPUT2 and RINPUT3)->"Right Input Mixer" will be powered down, but "Right ADC" is still powered up. Do you have some best method to set the audio route?
Thanks, Zidan Wang

I think your last patch that didn't touch DAPM for this was closer to correct, I would revert back to something similar to that but fixing up for the other comments on it.
