Hello guys,

I began with the implementation of a dapm mux and am almost done but I don't get how to configure the routes and I am not sure if I need more dapm definitions. As the capture stream is the source into the SE_IN_L/SE_IN_R I would say this should be the source for the left/right mux (right side of the route definition). Then I would need a switch in the middle and on the left side as the output should be the ADC1 (left side).

{ "ADC1", ADC1VINSWITCHLEFT, "SE_IN_L" }, I would think it should look something like this. But then I would need some SOC_DAPM_SINGLE, I think you can see I am clearly confused right now :)

I would like to have a mux where I can switch the vin source from vin1 to vin4 in alsamixer and then its saved as a default. Because in the layout plan the vin4 is connected and needs to be selected...

My code so far looks like this:

static const char * const pcm1863_adc_vinr_src[] = { "VIN1r", "VIN4r" }; /*Stereo ADC Source VIN1 left/right */ static SOC_ENUM_SINGLE_DECL( pcm1863_adc_vin1l_enum, PCM1863_ADC1_INPUT_SEL_L, PCM1863_SEL_L_VIN1_SFT, pcm1863_adc_vinl_src);
