Audio Codec WM8960 on TX2

Hi everybody,

I want to attach the ReSpeaker 2-Mics Pi Hat (http://wiki.seeedstudio.com/ReSpeaker_2_Mics_Pi_HAT) to an expansion header of a custom TX2 carrier board. Unfortunately it does not work. Our expansion header is nearly similar to the J21 header of the Jetson DevKit. The pins of the ReSpeaker board should be compatible, all used signals are provided on the header. So, from the hardware side, everything should be ok.

I tried the following steps to get the codec running:

  1. I activated the WM8960 driver in the kernel.
  2. I added the codec to the device tree:
i2c@c240000 {
    wm8960_codec: wm8960@1a {
        status = "okay";
        compatible = "wlf,wm8960";
        reg = <0x1a>;
    };
};
  1. I changed the rt565x_dai_link entry:
rt565x_dai_link: nvidia,dai-link-1 {
    link-name = "wm8960-playback";
    cpu-dai = <&tegra_i2s1>;
    codec-dai = <&wm8960_codec>;
    cpu-dai-name = "I2S1";
    codec-dai-name = "wm8960-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";
};
  1. I changed the audio routing to:
nvidia,audio-routing =
    "x Headphone", "x HP_L",
    "x Headphone", "x HP_R";

This is the output of dmesg:

As you can see, there is some problem with the codec link:

[    5.640157] tegra-snd-t186ref-mobile-rt565x sound: codec link not defined - codec not part of sound card

What is the reason for this? I don’t know how to continue therefore I would appreciate if someone could help me to solve this issue. Thanks!

Hello!

You can ignore the above warning, this is printed because the ‘rt565x-playback’ link no longer exists. See sound/soc/tegra-alt/tegra_t186ref_mobile_rt565x.c …

1154         idx = tegra_machine_get_codec_dai_link_idx_t18x("rt565x-playback");
1155         /* check if idx has valid number */
1156         if (idx == -EINVAL)
1157                 dev_warn(&pdev->dev, "codec link not defined - codec not part of sound card");

Really we should fix this and not assume that everyone is using this codec.

So the things to check are …

  1. Do you see the codec listed as a device under the I2C controller. You should se a device ‘1-001a’ under the following locations …
ls /sys/class/i2c-adapter/i2c-1/
sudo ls /sys/kernel/debug/regmap/
  1. Also check to see if the codec is listed under …
sudo cat /sys/kernel/debug/asoc/codecs

If it is there, then it is all initialised fine.

Regards,
Jon

Hi Jon,

thanks for your help.

Oh, I see.

Yes, I can see the device.

It is listed there as wm8960.1-001a.

So, everything is set up correctly? If yes, could you give me a hint how to play/record audio on the device? I tried the following but can not see any signal on the I2S0_SDOUT.

aplay -Dhw:1,0 sound.wav

Yes sounds like the codec is initialised and now just needs to be configured.

So the aplay command …

aplay -Dhw:1,0 sound.wav

Implies that you are playing audio via the ADMA interface 1 on Tegra. So we need to ensure that this is mux’ed to the I2S1 interface. To do this execute the command …

amixer -c 1 cset name="I2S1 Mux" "ADMAIF1"

Now the codec itself probably needs some configuration because there are usually multiple paths through which the audio can be routed. For example, to the HP or Speaker outputs, etc. Looking at the wm8940 codec driver, I see that there is a ‘PCM Playback Switch’. Do you see a mixer control for this?

amixer -c 1 controls | grep "PCM Playback Switch"

If so can you enable this?

amixer -c 1 cset name="PCM Playback Switch" on

Note I am not familiar with this specific codec so it is a bit of guess work!

Regards,
Jon

Thanks Jon, I can hear the sound on the headphones. I had to enable the “x Left Output Mixer PCM Playback Switch” and “x Right Output Mixer PCM Playback Switch”.

Now I tried to record something from the microphones. I mux’ed the I2S1 to the ADMA interface 1:

amixer -c 1 cset name="ADMAIF1 Mux" "I2S1"

After that, I tried to record something using the following command:

arecord -f cd hw:tegrasndt186ref,0 test.wav

Unfortunately, nothing is recorded. I also probed the I2S0_SDIN, I2S0_CLK, I2S0_LRCLK pins but can not see any signal. Also enabling the “x Capture Switch” did not help. Do you have any idea how to go on?

Thanks,
Markus

Oh, I forgot to add the audio routes for recording:

"x LINPUT1",		"x Mic",
"x LINPUT3",		"x Mic",
"x RINPUT1",		"x Mic",
"x RINPUT2",		"x Mic";

Now I can see the signals on the oscilloscope and arecord works. So, I think on Tegra side, everything should be ok now. Unfortunately, only silence is recorded. I will check, if I have to enable something else or to increase the capture volume…

Great! Yes check if the I2S din is toggling. If it isn’t then it is probably some codec configuration that we are missing, otherwise, it is on the Tegra side.

Regards,
Jon

hi jon
i have the same question with wm8960 on tx2,when I use aplay -Dhw:1,0 ltt20070412.wav,I can only see AUDIO_MCLK signals on the oscilloscope

1、I can see 1-001a when using
ls /sys/class/i2c-adapter/i2c-1/
sudo ls /sys/kernel/debug/regmap/
2、i also can see wm8960.1-001a when using
sudo cat /sys/kernel/debug/asoc/codecs
3、have any other command without amixer -c 1 cset name=“I2S1 Mux” “ADMAIF1”, not include the codecs configure

hi Mark
you said “I activated the WM8960 driver in the kernel.” Can i ask a few questions please?
1、have any modification in wm8960.c file in sound/soc/codecs dir
2、have any modification in tegra_t186ref_mobile_rt565x.c file expect
idx = tegra_machine_get_codec_dai_link_idx_t18x(“rt565x-playback”);
the dts config is like this

Hello!

Per Markus’ feedback in comment 5 above he also has to set the codec mixer controls …

amixer -c 1 cset name="x Left Output Mixer PCM Playback Switch" on
amixer -c 1 cset name="x Right Output Mixer PCM Playback Switch" on

Regards,
Jon

Hi dgw_1985,

I did not change the driver sources, neither the wm8960.c nor the tegra_t186ref_mobile_rt565x.c. As codec-dai-name I used “wm8960-hifi”, because this is the name used in the driver:

static struct snd_soc_dai_driver wm8960_dai = {
	.name = "wm8960-hifi",
	.playback = {
		.stream_name = "Playback",
		.channels_min = 1,
		.channels_max = 2,
		.rates = WM8960_RATES,
		.formats = WM8960_FORMATS,},
	.capture = {
		.stream_name = "Capture",
		.channels_min = 1,
		.channels_max = 2,
		.rates = WM8960_RATES,
		.formats = WM8960_FORMATS,},
	.ops = &wm8960_dai_ops,
	.symmetric_rates = 1,
};

Maybe you have to change it in your device tree?

Btw. I was finally able to record something. Nevertheless, I am not satisfied with the quality. It is really noisy and sometimes one can hear a clicking noise. Playback works well. I don’t know if the microphones are that bad or if there is still a configuration issue. Any idea?

Hi Markus,

Given that playback works fine, that would indicate that the I2S timing and the codec MCLK is configured fine. If you are using the same sample rate and sample size for playback and capture then the MCLK should be the same frequency.

To double check you can dump the I2S registers and clock settings during playback/capture and I can take a look to make sure it looks good …

sudo grep "i2s\|mclk\|ape\|ahub" /sys/kernel/debug/clk/clk_summary
sudo cat /sys/kernel/debug/regmap/tegra210-i2s.0/registers

If this looks OK, then maybe there is a codec setting that is not quite right?

Regards,
Jon

Sample rate for recording was set to 48000Hz. When I use another sample rate, I can only hear some clicking noise. Maybe it has something to do with the mclk? The mclk is generated directly on the audio module, that means the mclk provided by the Jetson is not used. Do I have to give the value somewhere in the device tree? Looking at the device tree overlay of the Raspberry Pi (https://github.com/respeaker/seeed-voicecard/blob/master/seeed-2mic-voicecard-overlay.dts), one can see that they provide the mclk as fixed clock. How can we do this on the Jetson, if necessary?

1、 “the codec-dai-name I used “wm8960-hifi”",this is a Wrongly written
2、how you activated the WM8960 driver in the kerne?,I tried the following steps to activated the codec,
can help check it out ?
a、cp tegra_t186ref_mobile_rt565x.c tegra_t186ref_adas_wm8960.c
b、modify DRV_NAME and compatible in tegra_t186ref_adas_wm8960.c file

#define DRV_NAME "tegra-snd-t186ref-adas-wm8960"
static const struct of_device_id tegra_t186ref_of_match[] = {
	{ .compatible = "nvidia,tegra-audio-t186ref-adas-wm8960", },
	{},
};

c、replace all the “rt565x-playback” with “wm8960-playback” in tegra_t186ref_adas_wm8960.c file

132         idx = tegra_machine_get_codec_dai_link_idx_t18x("wm8960-playback"); 
297         idx = tegra_machine_get_codec_dai_link_idx_t18x("wm8960-playback");
934         if (strstr(tegra_t186ref_codec_links[i].name,
935                                 "wm8960-playback"))
1114        idx = tegra_machine_get_codec_dai_link_idx_t18x("wm8960-playback");

38 obj-$(CONFIG_SND_SOC_TEGRA_T186REF_ADAS_ALT) += snd-soc-tegra-alt-t186ref-adas.o

f、modify the tegra18_defconfig

422 #CONFIG_SND_SOC_TEGRA_T186REF_MOBILE_ALT=y
423 CONFIG_SND_SOC_TEGRA_T186REF_ADAS_ALT=y
424 CONFIG_SND_SOC_TEGRA_T186REF_P4573_ALT=y
425 CONFIG_SND_SOC_TEGRA_T186REF_M3420_ALT=y

tks jon
this two command is setting codec pcm playback switch ,but i thinks when using aplay command,the i2s_out can see signals on the oscilloscop,even if the codec is not right config

amixer -c 1 cset name="x Left Output Mixer PCM Playback Switch" on
amixer -c 1 cset name="x Right Output Mixer PCM Playback Switch" on

Hi Markus,

If the MCLK is not provided by Jetson, then you should configure the codec to be the bitclock-master and frame-master in DT. The issue is mostly likely that the clocks between the codec and Tegra are not in sync.

Looking at comment #1 above you have the codec as bitclock-slave and frame-slave so try changing to bitclock-master and frame-master and see if this help.

Regards,
Jon

Hi Jon,

after changing the configuration to bitclock-master and frame-master, I get the following error message:

[ 1966.505724] wm8960 1-001a: No SYSCLK configured

Do I have to provide the clock somewhere in the device tree?

Thanks,
Markus

@dgw_1985:

I just enabled the driver with:

CONFIG_SND_SOC_WM8960=y

After that, I did the changes in the device tree which were written in comment #1. Nothing else. I did not had to change any line of code in the driver.
After booting you have to mux the i2s to the adma interface

amixer -c 1 cset name="I2S1 Mux" "ADMAIF1"

and enable the playback switches:

amixer -c 1 cset name="x Left Output Mixer PCM Playback Switch" on
amixer -c 1 cset name="x Right Output Mixer PCM Playback Switch" on

With this procedure, I got the playback working.

MarkusHeß

tks for reply,are you using R28.2?

yes

Hi Markus,

The above I2S error occurs when the I2S port does not receive a bit clock from the codec and so the software reset of the I2S interface fails. Yes, given that the wm8960 reports ‘No SYSCLK configured’ we need to tell the wm8960 driver what is driving the mclk. So in the Tegra186 audio machine driver we would need to do something like this, replacing ‘’ with the actual frequency that the on-board oscillator is driving the mclk (which may be 12000000Hz or whatever) …

Ok, I tried the changes, but now I get the following output:

[   48.813898] wm8960 1-001a: failed to configure clock
[   48.824177] wm8960 1-001a: ASoC: Failed to prepare bias: -22

I’m not sure, if I used the correct clock. Looking at the schematics, I can see an oscillator with 24 MHz, so I tried 24000000. In the Raspberry Pi device tree overlay, the clock frequency is set to 12288000. I tried both with no success.
