TLV320aic32x4 audio codec is not detecting for tx2i

Hello!

Please ensure that the ‘prefix’ specified under the dai-link in DT for the codec matches what you have in the nvidia,audio-routing. So if the prefix is ‘z’, then you want …

nvidia,audio-routing =
            "z Headphone", "z LOL",
            "z Headphone", "z LOR",
            "z IN1_L",           "z Mic",
            "z IN1_R",           "z Mic";

If it is ‘x’, then you need to replace ‘z’ with ‘x’.

Regards.
Jon

Hello Jonathanh,

yes, I got it now. error is solved.
But I’m not able to see the sound output in the setting.

My target is should play some sound with the audio codec and should show in the sound setting.

Hello!

A couple questions …

  1. Have you configured the MCLK to output 12MHz? This needs to be configured in device-tree. To check you can …
$ sudo grep aud_mclk /sys/kernel/debug/clk/clk_summary
  1. Have you configured the codec? Igal posted some playback and capture scripts which configure the appropriate mixer controls for the codec. It is recommended that you try his scripts for playback/capture.

Jon

Hello!

You need to configure the aud_mclk, otherwise it will not work.

Jon

Hello Jonathanh,

Thank you. Could you please tell me where can I update the aud_mclk whetherin DT or tlv.c or Tegra mobile.c

Regards,
Parashuram

Hello!

Please refer to this comment.

Jon

Hello Jonathanh,

I have followed this wiki Added TLV sysclk
file is tegra_machine_driver_mobile.c

+//Added tlv320aic32x4
+static int tegra_machine_aic32x4_init(struct snd_soc_pcm_runtime *rtd)
+{
+	struct device *dev = rtd->card->dev;
+   	int err;
+
+	err = snd_soc_dai_set_sysclk(rtd->codec_dai, AIC32X4_FREQ_12000000, 12000000,
+                        SND_SOC_CLOCK_IN);
+    if (err) {
+        dev_err(dev, "failed to set aic32x4 sysclk!\n");
+        return err;
+    }
 
+    return 0;
+}
+//Ended

Igle code complete different that all are old file think that is L4T 28 right now we are using L4T 32.4.4 so it has lot difference.
could you please let me know how to update the aud_mclk for TLV.
please find the made changes in tegra_machine_driver_mobile.ctegra_machine_driver_mobile.c.txt (3.6 KB)

Is there anything to add for AUD_MCLK ? I’m not clear could you please help me out.

regards,
Parashuram

Hello!

Per the document the format of assigned-clock-rates is …

   assigned-clock-rates = <0>, <desired_fixed_rate>;desired_fixed_rate1

And so you need …

   assigned-clock-rates = <0>, <12000000>;

Once this is configured correctly, you should see the correct rate in the clk_summary.

Regards,
Jon

You also need to check the pinmux settings for the aud_mclk and dap1 pins. See this post and this post.

Hello!

The pinmux settings still do not look correct, because they all are default to the ‘rsvd1’ function. So you need to update the function in the pinmux spreadsheet appropriately for the I2S and AUD_MCLK functions.

With regard to the clocks. You want the pll_p_out0 to drive the AUD_MCLK and so you want …

                assigned-clocks = <&tegra_car TEGRA186_CLK_PLL_A_OUT0>, <&tegra_car TEGRA186_CLK_AUD_MCLK>;
                assigned-clock-parents = <&tegra_car TEGRA186_CLK_PLLA>, <&tegra_car TEGRA186_CLK_PLLP_OUT0>;
                assigned-clock-rates = <0>, <12000000>;

Hello!

Great! What is the parent clock and frequency reported for the aud_mclk now?

Also can you confirm what you currently have in the dai-link node for the codec? We need to make sure that the codec is the bit clock and frame-sync master.

Hello Jonathanh,

Hello!

Sorry, if I was not clear, I mean can you show the aud_mclk parent and rate as reported in the sysfs to ensure that it is actually configured as expected …

$ sudo cat /sys/kernel/debug/clk/aud_mclk/clk_parent
$ sudo cat /sys/kernel/debug/clk/aud_mclk/clk_rate

Hopefully, the above now align with what you have in DT.

For the dai-link, you should set replace ‘bitclock-slave’ and ‘frame-slave’ and ‘bitclock-master’ and ‘frame-master’ because we want the codec to be the master. See Igal’s configuration.

Jon

Hello!

That all looks good. Have you tried Igal’s playback and capture scripts?
