I use the tlv320aic3109 decoder
reference https://devtalk.nvidia.com/default/topic/1036139/jetson-tx2/tx2-asoc-with-tlv320aic32x4/1

This is a probe defer error (-517) which can be normal if the codec has not yet been registered. The kernel should try to probe the sound driver again later. If the codec is never registered then you will see these messages repeated several times until the kernel boots. It would be helpful if you could attach the complete kernel dmesg output and device-tree changes that you have made.

Regards,
Jon

Yes, the codec is not registered successfully.

Can you please clarify the audio codec you are using? I don’t see a tlv320aic3109 on the TI website.

The reason I ask is because there are two drivers …

  1. sound/soc/codecs/tlv320aic3x.c
    This driver is compatible with the following devices …
    “ti,tlv320aic3x” - Generic TLV320AIC3x device
    “ti,tlv320aic33” - TLV320AIC33
    “ti,tlv320aic3007” - TLV320AIC3007
    “ti,tlv320aic3106” - TLV320AIC3106
    “ti,tlv320aic3104” - TLV320AIC3104

  2. sound/soc/codecs/tlv320aic31xx.c
    This driver is compatible with the following devices …
    “ti,tlv320aic310x” - Generic TLV320AIC31xx with mono speaker amp
    “ti,tlv320aic311x” - Generic TLV320AIC31xx with stereo speaker amp
    “ti,tlv320aic3100” - TLV320AIC3100 (mono speaker amp, no MiniDSP)
    “ti,tlv320aic3110” - TLV320AIC3110 (stereo speaker amp, no MiniDSP)
    “ti,tlv320aic3120” - TLV320AIC3120 (mono speaker amp, MiniDSP)
    “ti,tlv320aic3111” - TLV320AIC3111 (stereo speaker amp, MiniDSP)
    “ti,tlv320dac3100” - TLV320DAC3100 (no ADC, mono speaker amp, no MiniDSP)

Looking at your dmesg log, the reason why the codec is not registered is because the supplies are missing from the device-tree binding …

[    3.743213] regulator_get() failed for (1-0018,IOVDD), -19
[    3.743217] tlv320aic3x-codec 1-0018: Failed to get supply 'IOVDD': -19
[    3.743220] tlv320aic3x-codec 1-0018: Failed to request supplies: -19

However, before we try to fix the above, let’s clarify exactly what codec you are using so we know we are using the correct driver.

Regards,
Jon

TI’s reply is TLC320AIC3X
Tlv320aic3109 is similar to tlv320aic3104

7

The power of IOVDD should be 3.3V
Where should I add?

8

Where can I find this device on the TI website?

Jon

OK, is the codec on some TI evaluation board that is connected to the Jetson? If so then the codec is most likely powered by its own supply and therefore, we would need to have some sort of dummy regulator in device-tree because it is not a regulator that Tegra can control. I wonder if something like the following would work (not tested) …

Strangely, I can see 3 i2c addresses by plugging in the device

Can you ensure that ‘CONFIG_REGULATOR_DUMMY’ is enabled in the kernel configuration (arch/arm64/configs/tegra18_defconfig)? You can check by …

$ zcat /proc/config.gz | grep REGULATOR_DUMMY

Please attached the complete dmesg output.

Thanks
Jon

The good news, according to your suggestion, the problem is solved.
But there is still no sound and the pulse can be seen on the logic analyzer. Is my setting incorrect?

Hello!

Yes the routing looks OK to me. Are you trying playback or record? If you need both, let’s start with playback and work on record next.

For playback are you using the headphone or line-out outputs? I see you have both included in the route, but which interface are you using on the board?

Can you trace the DAPM power widgets when starting playback/capture?

Hello!

Looks like the audio route is still not complete and the I2S interface is not being enabled. Can you run the attached script and send the output file generated?

Thanks

Can you respond to the above questions so I understand what you are testing and what interface on the codec you are using?
