The audio codec es8316 can’t work on I2S0 for Xaiver NX

Hi, Engineers
dmesg.txt (91.3 KB)
es8316.c (38.1 KB)
tegra_machine_driver_mobile.c (24.3 KB)
tegra194-audio-p3668.dtsi (2.1 KB)

The audio chip has been successfully registered in our system, but it can’t work normally. There is no sound when playing music.
Measure I2S_LRCK and I2S_SDO and I2S_SCK with an oscilloscope and there is no signal, Only I2S_MCK has a signal, Here are the pictures



es8316.c and DTS and dmesg links are also placed above.

Hi:
Now I2S_MCK , I2S_SCK , I2S_LRCK have signals here, But es8316 there was still no sound , some problem with routing

1. es8316 I2C dts is here:

Hi @wangxiaozhuang, This is the wrong category for your issue. I am moving this topic from the Triton Inference Server category to Jetson Xavier NX.

Thanks for your reply, I have created a topic here, very eager for support, thank you again

Hi wangxiaozhuang,

Can you please check by updating the correct dtsi file?

Step [3] above points to tegra186-p3636-0001-a00-audio.dtsi. You need to modify tegra194-audio-p3668.dtsi, as you originally posted. Please add the related routing controls and share your observations.

Thanks,
Sameer.

Hi spujar,
We have made three products with the same base plate. NX, TX2 and Nano, they are the same phenomenon, 2S_ MCK , I2S_ SCK , I2S_ LRCK pins have signals but no sound:

Thanks a lot,
wangxiaozhuang.

Hi wangxiaozhuang,

The issue you are facing may be similar to all the products. To make it simpler you can test on one product to start with and similar fix may help remaining products as well.

Lets consider TX2 for example ( tegra186-p3636-0001-a00-audio.dtsi):

  • I checked the codec datasheet (https://www.alldatasheet.com/datasheet-pdf/pdf/1132837/EVEREST/ES8316.html). The MCLK clock seems to expect 256*fs. Any specific reason why you are using fixed 12.288 MHz clock? Can you please check once by making this a function of sample rate?

  • As per your earlier comment, clocks are fine. What is the configuration you are testing (sample rate, channels or sample size)? Also please double check if you are getting expected clock frequencies.

  • Do you intend to operate codec in master mode? If this is not a strict requirement can you check once with codec slave mode?

  • Do you see any errors when you run playback? Does playback run for expected duration and there is no audio at all? Please share logs in case of errors.

Thanks,
Sameer.

Hi, spujar,

  • I have changed MCLK to 2.8MHz, but it doesn’t work , The default clock is 11.30MHz,when I play music on the command line, it becomes 12.30Mhz

Why you want to change MCLK to 2.8 MHz?
Generally MCLK = 256 * fs (where fs is sample rate) = 256 * 48000 = 12288000 Hz
The driver sets this rate at runtime. See below:

rtd = snd_soc_get_pcm_runtime(card, "es8316-playback");	//wxz
	if (rtd) {
printk("%s===========8316================== %d\n",__func__,__LINE__);
		dai_params =
		(struct snd_soc_pcm_stream *)rtd->dai_link->params;

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

		err = es8316_set_dai_sysclk(rtd->codec_dai, ES8316_SCLK_S_MCLK,
					     aud_mclk, SND_SOC_CLOCK_IN);
		if (err < 0) {
			dev_err(card->dev, "codec_dai clock not set\n");
			return err;
		}
	}

Do you need a different frequency? Don’t worry about init, it gets overridden at runtime based on the sample rate you run.

There is nothing like"bitclock-slave" or “frame-slave”. You can just drop the “bitclock-master” and “frame-master” from the DT. But what you did should also make the Tegra I2S master. Don’t worry about the initial clock rates. When you start playback, check if all clocks are as expected.

I checked this dump. It seems to have following controls.

Simple mixer control 'z Right Hp mixer RLIN',0

Above controls are related to your codec es8316? I see “z” as prefix. But the DT you pointed earlier uses “x” prefix for mapping machine and codec widgets. Can you please correct this mapping and then check?

Everything else seem normal. Please confirm the codec side mixer settings are fine, because it is difficult for me to guess what exactly is required for codec mixer controls.

Thanks,
Sameer.

Hi,
Very sorry for the late response, I asked for leave a few days ago.

  • I found a product that also uses es8316, measuring his MCLK is 2.8MHz is due to my measurement position error ,the correct value is 11.4MHz.

  • After I remove “bitclock-master” and “frame-master”, MCLK is still 11.30MHz.

Hi wangxiaozhuang

This file is not readable. Can you please attach the correct file?

You are playing 48kHz/2-channel/16-bit audio stream. The expected MCLK clock is 12.288 MHz. As per your previous update, this clock was correct (~12.3 MHz). Can you confirm this again? Note that you need to probe the clocks after your run the speaker-test.

Thanks,
Sameer.

Hi,

  • So sorry, this is the correct file:
    tegra194-audio-p3668.dtsi (3.4 KB)

  • I reconfirmed that it was 11.3MHz before running “speaker-test” and ~12.3MHz after running “speaker-test”.

Thanks,
wangxiaozhuang

Hi,Sameer
I have a few more questions.

1, Why are there so many sound cards here, can they all work? Can I remove other ADMAIFx and keep only one ADMAIF1? Because es8316 only sees one sound card on other CPUs.

  • Run the ”sperker-test“ program, MCLK is still 12.3MHz, the audio output pin “I2S_ SDO” has no data. Any suggestions? I look forward to your reply .

Hi wangxiaozhuang,

12.3 MHz is expected rate once you start the speaker-test. So from clocking point of view it appears good.

What you see here are the playback or capture HW devices. Multiple devices can be used when there is a requirement of multiple stream playback or capture (For ex: ADMAIF1, ADMAIF2 …). You don’t have to worry about this. Your case may require just one device (ADMAIF1) and you can just use that. You can check following to see number of available sound cards:
cat /proc/asound/cards

Don’t modify this.

This looks incorrect. Can you try with following?

Before you run speaker-test, set up audio path.

amixer -c es8316tegra "I2S5 Mux" "ADMAIF1"
speaker-test -D hw:es8316tegra,0 -c 2 -r 48000 -F S16_LE -t sine -f 500

Also are you checking playback on speaker or headphone? I see es8316 has some switch controls for headphone path. Try turning these switches ON before you start speaker-test.

numid=1143,iface=MIXER,name='x Left Hp mixer LLIN Switch'
  ; type=BOOLEAN,access=rw------,values=1
  : values=off
numid=1144,iface=MIXER,name='x Left Hp mixer Left DAC Switch'
  ; type=BOOLEAN,access=rw------,values=1
  : values=off
numid=1145,iface=MIXER,name='x Right Hp mixer RLIN Switch'
  ; type=BOOLEAN,access=rw------,values=1
  : values=off
numid=1146,iface=MIXER,name='x Right Hp mixer Right DAC Switch'
  ; type=BOOLEAN,access=rw------,values=1
  : values=off

Once you start speaker-test, you should see pcm_startup() and hw_param() calls from your codec driver. Keep those debug prints enabled as you have now.

Thanks,
Sameer.

Hi wangxiaozhuang,

Can you please confirm if you are testing on heapdhone?

**This points to some DAPM routing problem. This needs to be fixed before you proceed.
I had a look at es8316 codec driver. The “I2S IN” widget seems to use “I2S1 Playback” stream which I don’t find in the codec driver. Can you try if below helps?

The DAPM trace logs you captured in previous comment is incomplete. Please enable trace events before you start speaker-test. Dump the trace logs once the speaker-test is done.

Also try with following controls only:

numid=1144,iface=MIXER,name='x Left Hp mixer Left DAC Switch'
  ; type=BOOLEAN,access=rw------,values=1
  : values=on
numid=1146,iface=MIXER,name='x Right Hp mixer Right DAC Switch'
  ; type=BOOLEAN,access=rw------,values=1
  : values=on

Thanks.

Hi, Sameer

Thank you very much. Great progress has been made according to your guidance

  1. Both heapdone and speaker are connected to sound output devices.

  2. Run the “speaker-test” and the signals can be detected on “I2S_MCK” “I2S_SCK” “I2S_SDO” and “I2S_LRCK” pins.

amixer -c es8316tegra cset name="I2S5 Mux" "ADMAIF1"
amixer -c es8316tegra cset name="x Left Hp mixer Left DAC Switch" 1
amixer -c es8316tegra cset name="x Right Hp mixer Right DAC Switch" 1

  1. The frequency of "I2S_ SCK” and “I2S_LRCK ” are correct?

I2S_MCK:


I2S_SCK:

I2S_SDO:

I play music with “aplay”, the frequencies of “I2S_MCK” “I2S_SCK” and “I2S_LRCK” are 5.65Mhz, 706KHz and 22KHz respectively. Is that normal ?

aplay -D hw:es8316tegra music.wav 
Playing WAVE 'music.wav' : Signed 16 bit Little Endian, Rate 22050 Hz, Stereo

This playback is the same result, and the kernel throws an exception after playing for a while:

I guess the music “music.wav” is over.

Thanks
wangxiaozhuang

Hi wangxiaozhuang,

It is looking better.

Yes the clock frequencies seem to be correct. This confirms pinmux, driver and DT settings are fine.

You have to enable asoc events related to DAPM path. Please refer to section.

I hope you are getting codec pcm_startup() and hw_param() calls now. Can you please confirm?

I don’t know the stream configuration of music.wav and hence won’t be able to comment on this.
Test with below stream (it is 48000 Hz, 2-channel and 16-bit) and you should see the same clock frequencies with what you were getting for speaker-test run earlier.

Yes the music is probably over and the codec driver crashes when it finishes.

Thanks.

Hi,Sameer
Play your wav file and the clock is correct, but the codec driver is also broken, why ?

You may want to check the codec crash with codec vendor. Also confirm the codec settings with them. I see there is a mute() call from codec. Please make sure that the audio is not really muted. You can also check with increasing playback volume from codec mixer control settings.

From clock, driver and DT setup wise things look good. You are able to get the required clocks and able to get expected driver callbacks. There is data signal on SDO line as well.
