Hello!
You also need to ensure that you have configured the capture mux as well.
amixer -c jetsonxaviernxa cset name="ADMAIF2 Mux" I2S3
arecord -D hw:jetsonxaviernxa,1 <args> <wav>
By default sub-device0 is muxed to I2S5 and so when using that subdevice, you will not see an error.
Regards,
Jon
Hi Jonathan,
Sorry I have edited my question. I tried the same commands you had mentioned. I am getting the below error.
arecord -D hw:jetsonxaviernxa,1 -r 16000 -c 1 -d 10 -f S16_LE out.wav
Recording WAVE ‘out.wav’ : Signed 16 bit Little Endian, Rate 16000 Hz, Mono
arecord: pcm_read:2103: read error: Input/output erro
Hi Jonathan,
I tried playing an audio file,
amixer -c jetsonxaviernxa cset name=“I2S3 Mux” ADMAIF1
aplay -D hw:jetsonxaviernxa,0 100Hz_44100Hz_16bit_05sec.wav
below is the debug log for the same,

We use I2S3 instance. Does the audio routing look fine?
For recording, as I had mentioned we are getting an error.
amixer -c jetsonxaviernxa cset name=“ADMAIF1 Mux” I2S3

Hi,
Probing I2S1_SCLK we do not see any clock. It is always 0.
Please find the pinctrl.

Hello!
For the playback case, make sure that you don’t have the I2S5 muxed to the ADMAIF1 as well …
$ amixer -c jetsonxaviernxa cset name=“I2S5 Mux” None
$ amixer -c jetsonxaviernxa cset name=“I2S3 Mux” ADMAIF1
On the record side the route is not complete because as you can see the DMA interface is not routed to the I2S and codec …

If you do something like this you can see the connections between all the dapm widgets …
dapm_dirs=$(sudo find /sys/kernel/debug/asoc -type d -name dapm)
for dir in ${dapm_dirs}; do
sudo find ${dir} -type f -exec echo {} \; -exec cat {} \;
done

Hi Jonathan,
I guess the play doesnt work too.

Hello!
Yes that is what I expected. Given that the codec driver does not have any DAPM widgets and route defined by default, I am wondering if you actually just need the I2S interface to drive the pins? If so, then you should be able to using the default dummy spdif codec in the ‘nvidia,dai-link-3’ and not modify this.
The only reason you would need to add the codec to the route is if there is something that needs to be enabled in the codec when the I2S interface is turned on.
Regards,
Jon
Hi Jonathan,
So are you telling to retain the nvidia,dai-link-3 node as it is?
nvidia,dai-link-3 {
link-name = "spdif-dit-2";
cpu-dai = <&tegra_i2s3>;
codec-dai = <&spdif_dit2>;
cpu-dai-name = "I2S3";
codec-dai-name = "dit-hifi";
format = "i2s";
bit-format = "s16_le";
srate = <48000>;
num-channel = <2>;
ignore_suspend;
name-prefix = "z";
status = "okay";
};
?
Hello!
Yes, I was wondering if we could leave the node as-is. There are some simple I2S codecs that do not require any configuration at runtime, however, looking again at the driver I do see it has a hw_params callback and so we need to ensure that this gets called when playback/capture is started. So no we cannot leave the dai-link-3 node as it is and we need to modify like you have done. So we just need to figure out what is wrong with the route.
Jon
Hi Jonathan,
Awesome! It works.
I left the node as it is. We were able to get the I2S signals. The recorded audio is not proper. We are verifying it.
Thankyou for addressing our queries.
Hi Jonathan,
I had left the node as it is. And i was able to get the I2S signals while recording and playing. But the recorded audio is not proper. We couldn’t verify the played audio yet.
hw_params is not getting called on playback/capture.
Hello!
That is good news. Yes I think that we want hw_params to be called to set the format correctly. To do that, we would need to modify the dai-link and figure out why the route is not completed. In the case where it does not work with the modified dai-link, if you could share the output from the following, we might be able to see what is going wrong …
dapm_dirs=$(sudo find /sys/kernel/debug/asoc -type d -name dapm)
for dir in ${dapm_dirs}; do
sudo find ${dir} -type f -exec echo {} \; -exec cat {} \;
done
Jon
Hi Jonathan,
I modified the dai-link, added the component driver parameter in driver, retained the audio routing configuration in device tree as such. It looks like its working now.
nvidia,audio-routing =
"x Headphone", "x OUT",
"x IN", "x Mic",
"y Headphone", "y OUT",
"y IN", "y Mic",
"z Headphone", "z OUT",
"z IN", "z Mic",
"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",
"d1 Headphone", "d1 OUT",
"d2 Headphone", "d2 OUT";
nvidia,dai-link-3 {
link-name = "zl380tw0-playback";
codec-dai = <&codec>;
codec-dai-name = "zl380tw0-hifi";
cpu-dai-name = "I2S3";
};
static const struct snd_soc_dapm_widget dit_widgets = {
SND_SOC_DAPM_OUTPUT(“OUT”),
SND_SOC_DAPM_INPUT(“IN”),
};
static const struct snd_soc_dapm_route dit_routes = {
{ “OUT”, NULL, “Playback” },
{ “Capture”, NULL, “IN” },
};
static struct snd_soc_codec_driver soc_codec_dev_zl380tw = {
.component_driver = {
.dapm_widgets = dit_widgets,
.num_dapm_widgets = ARRAY_SIZE(dit_widgets),
.dapm_routes = dit_routes,
.num_dapm_routes = ARRAY_SIZE(dit_routes),
},
We tried probing the I2S lines while aplaying. We get clock,ws and data.
But while recording, we get a blank wav file. Tried probing the I2S lines. We get only the clock and ws. No data is obtained.
Hello!
Sounds like you are making good progress. Previously you mentioned that the pinmux for din is …
Bank: 0 Reg: 0x02431050 Val: 0x00000450 -> dap3_din_pt3
This has the input-enable set for the DIN pin and so this configuration looks good. From what you are saying it should like the codec is not outputing any data, if this is the case, then you need to review the codec configuration to see if it is configured correctly.
Regards,
Jon
Hi Jonathan,
Thankyou for your reply.
We are looking into the codec configuration.
We see the below error in dmesg
[ 2.080820] tegra-asoc: sound: ASoC: CODEC DAI zl380tw0-hifi not registered
[ 2.081072] tegra-asoc: sound: snd_soc_register_card failed (-517)
Why is it so?
Hello!
The error code -517 is EPROBE_DEFER and simply means that a resource that the codec needs (such as a clock) is not available yet and so retry the probe of the codec again later. As long as the codec is eventually probed successfully you can ignore these warnings. I recently sent a patch to silence these warnings on more recent kernels because they are mis-leading.
Regards,
Jon
Hi Jonathan,
Thankyou Jonathan for all help. We are able to record and play audio.
