Hi,
I have linein and mic in my codec and a mux which takes these two inputs and feeds to adc.
So I added this mux as: static const char *sn95031_mic_texts[] = { "amic", "linein" };
static const struct soc_enum sn95031_micl_enum = SOC_ENUM_SINGLE(SN95031_ADCCONFIG, 1, 2, sn95031_mic_texts);
And in my dapm_widget array: SND_SOC_DAPM_MUX("Input MICL", SND_SOC_NOPM, 0, 0, &sn95031_micl_mux_control),
I saw at few place in existing codecs that text in MUX (user selection) can be used as path element (let me know if that's incorrect)
So I added : { "MIC1 Enable", "amic", "ADC Left"}
You need to specify the route like: { "Input MICL", "amic", "ADC Left"}
So, if the "Input MICL" MUX is in amic position, it will connect to "ADC Left"
But while adding the routes it returns an error that "sn95031: Failed to add route ADC Left->MIC1 Enable "
Since the "MIC1 Enable" widget does not have the amic route, I believe.
