This is the log as ti,audio-routing: we are using Am335x processor, 3.14 kernel --

in the Audio Dac Example in the wikipedia:

The snd_soc_dapm_widget and snd_soc_dapm_route structures are not going to be utilized in this case; they there if power management capabilities are taken into account. These structures can be deleted.

can we delete the widgets and damp_route structures: below is the structure from davinci-evm.c

/* davinci-evm machine dapm widgets */
static const struct snd_soc_dapm_widget aic3x_dapm_widgets[] = {
   SND_SOC_DAPM_HP("Headphone Jack", NULL),
   SND_SOC_DAPM_LINE("Line Out", NULL),
   SND_SOC_DAPM_MIC("Mic Jack", NULL),
   SND_SOC_DAPM_LINE("Line In", NULL),
};

/* davinci-evm machine audio_mapnections to the codec pins */
static const struct snd_soc_dapm_route audio_map[] = {
   /* Headphone connected to HPLOUT, HPROUT */
   {"Headphone Jack", NULL, "HPLOUT"},
   {"Headphone Jack", NULL, "HPROUT"},

   /* Line Out connected to LLOUT, RLOUT */
   {"Line Out", NULL, "LLOUT"},
   {"Line Out", NULL, "RLOUT"},

   /* Mic connected to (MIC3L | MIC3R) */
   {"MIC3L", NULL, "Mic Bias"},
   {"MIC3R", NULL, "Mic Bias"},
   {"Mic Bias", NULL, "Mic Jack"},

   /* Line In connected to (LINE1L | LINE2L), (LINE1R | LINE2R) */
   {"LINE1L", NULL, "Line In"},
   {"LINE2L", NULL, "Line In"},
   {"LINE1R", NULL, "Line In"},
   {"LINE2R", NULL, "Line In"},
};

as i given the ti, audio routing in the dts file as like this :

        ti,audio-routing =
           "Headphone Jack",       "HPLOUT",
           "Headphone Jack",       "HPROUT",
           "Line Out",             "LLOUT",
           "Line Out",             "LROUT";

please any one help in this --

Hi Don ,

these two post are different scenario's --
1. Earlier post is belongs to loading/adding a new codec driver.
2. this post is about after successful adding a new codec driver -- audio routing related issues -- which is given in device tree file and those will come to davinci-evm.c -- and this file is also done for tlv320aic3106 only -- which is default one with EVM-SK board -- which is successfully loaded in EVM-SK board and audio is also coming and too loaded in our custom board also -- but NO sound -- becoz of the registers are different from tlv320aic3106 and to tlv320aic3100/tlv320dac3100(almost these two are same with 1 or 2 features).

here we are facing the problem -- while adding a new audio codec driver --
As the Audio DAC eaxmple -- wiki is covering only up to -- adding/loading a new codec driver --

One point i felt very strange -- TI only not giving support for the TI - products. then who else ... here i am not having words to say..

I am struggling from 10 days to bring-up new audio-codec.. if at all having -- FULL description -- for the Audio codec as various codec features -- why we have to post -- in the community. we will only do.

Dont mind for my words... those are came from the issues that i faced from last 10 days.

I need to say thank to you , at-least you replied for the post. Thanks once again.

Viswanath K
