Ti TLV320AIC3101 cannot capture and play sound

Hello everybody,
I designed a board used aic31 and I2S0.I used a driver (not alsa structure) test the hardware is ok.Then I want to use the alsa structure code tlv320aic3x.c in kenerl.I changed the tegra186-quill-common.dtsi as follows
nvidia,audio-routing =
“z LINE2L”, “z IN”,
“z LINE2R”, “z IN”,
“z HPLOUT”, “z OUT”,
“z HPROUT”, “z OUT”
/* “x Headphone”, “x OUT”,
“x IN”, “x Mic”,
“y Headphone”, “y OUT”,
“y IN”, “y Mic”,
“z IN”, “z OUT”,
“m Headphone”, “m OUT”,
“m IN”, “m Mic”,
“n Headphone”, “n OUT”,
“n IN”, “n Mic”,
“o Headphone”, “o OUT”,
“o IN”, “o Mic”,
“a IN”, “a Mic”,
“b IN”, “b Mic”,
“c IN”, “c Mic”,
“d IN”, “d Mic”,
“e Headphone”, “e OUT”,
“e IN”, “e Mic”,
“d1 Headphone”, “d1 OUT”,
“d2 Headphone”, “d2 OUT”*/;

	nvidia,xbar = <&tegra_axbar>;
	/*
	rt565x_dai_link: nvidia,dai-link-1 {
		link-name = "rt565x-playback";
		cpu-dai = <&tegra_i2s1>;
		codec-dai = <&spdif_dit0>;
		cpu-dai-name = "I2S1";
		codec-dai-name = "dit-hifi";
		format = "i2s";
		bitclock-slave;
		frame-slave;
		bitclock-noninversion;
		frame-noninversion;
		bit-format = "s16_le";
		bclk_ratio = <0>;
		srate = <48000>;
		num-channel = <2>;
		ignore_suspend;
		name-prefix = "x";
		status = "okay";
	};

I chaned the tegra_t186ref_mobile_rt565x.c as follws
SND_SOC_DAPM_LINE( “z IN”, NULL),
SND_SOC_DAPM_LINE( “z OUT”, NULL),SND_SOC_DAPM_LINE( “z IN”, NULL),
SND_SOC_DAPM_LINE( “z OUT”, NULL),
idx = tegra_machine_get_codec_dai_link_idx_t18x(“ti-capture”);
/* check if idx has valid number */
if (idx != -EINVAL) {
dai_params =
(struct snd_soc_pcm_stream *)card->rtd[idx].dai_link->params;

	dai_params->rate_min = clk_rate;
	dai_params->formats = (machine->fmt_via_kcontrol == 2) ?
                            (1ULL << SNDRV_PCM_FORMAT_S32_LE) : formats;

	if (!machine->is_codec_dummy) {
		/*err = snd_soc_dai_set_sysclk(card->rtd[idx].codec_dai, RT5659_SCLK_S_MCLK, clk_out_rate, SND_SOC_CLOCK_IN);*/
		err = snd_soc_dai_set_sysclk(card->rtd[idx].codec_dai, 0, 12000000, SND_SOC_CLOCK_IN);
		if (err < 0) {
			dev_err(card->dev, "codec_dai clock not set clk_out_rate-%d\n", clk_out_rate);
			return err;
		}
	}
}

I think the changes is ok.The boot log as follows

I enter the following command,it cannot capture sound,but no error reported.I don’t know how to eliminate the problem,thank you!

Hello everybody,
Today I find the SCLK and LRCLK is no clock.Before I changed these files the clock is ok.I am confused.

Hello!

So there are a few things you need to look at here …

MCLK
In the above you are telling the codec that the MCLK is 12MHz. Is this MCLK provided by an external oscillator or Tegra? If it is provided by the Tegra ‘aud_mclk’ then this clock needs to be configured to operate at 12MHz. If it is an external oscillator connected to the codec, then there is no more to be done here.
Device-tree configuration
The above device-tree snippet has (although it is unclear if this commented out) …

rt565x_dai_link: nvidia,dai-link-1 {
        link-name = "rt565x-playback";
        cpu-dai = <&tegra_i2s1>;
        codec-dai = <&spdif_dit0>;
        cpu-dai-name = "I2S1";
        codec-dai-name = "dit-hifi";
        format = "i2s";
        bitclock-slave;
        frame-slave;
        bitclock-noninversion;
        frame-noninversion;
        bit-format = "s16_le";
        bclk_ratio = <0>;
        srate = <48000>;
        num-channel = <2>;
        ignore_suspend;
        name-prefix = "x";
        status = "okay";
};

There are a couple items here …

i). The ‘codec_dai’ and ‘codec_dai_name’ need to be updated to reference the codec you are using. For example see …

https://devtalk.nvidia.com/default/topic/1036828/jetson-tx2/sound-card-transplantation/post/5268266/#5268266

ii). In device-tree you are configuring the codec as the SCLK/LRCK slave. If the codec is being provided a 12MHz external clock, then this implies that you are using the codec’s internal PLL to generate the audio clocks. In this case, the codec should be the SCLK/LRCK master and not slave you should update the device-tree to have the following for the appropriate dai-link …

bitclock-master;
        frame-master;

iii). Have you updated the ‘nvidia,audio-routing’? If not you need to update. For example …
https://devtalk.nvidia.com/default/topic/1036828/jetson-tx2/sound-card-transplantation/post/5268809/#5268809

3). Codec configuration
The final thing that trips people up is configuring the codec. For a similar TI codec we did the following to get the line-out working …
https://devtalk.nvidia.com/default/topic/1036828/jetson-tx2/sound-card-transplantation/post/5269448/#5269448

Hope this helps.

Hi jonathanh，
Thank you.I read the link,my problem is different.When I change file to #1, SCLK and LRCLK is no clock.Now I have changed all files back.I plan to not use another way.I write a driver just to configure register not use ALSA,it seems easier to me.
