TLV320AIC3109-Q1: No sound in audio recording

Part Number: TLV320AIC3109-Q1

Hello,

I want to use the TLV320AIC3109 audio codec on my custom i.MX8M board.

I have two microphones connected on Line1 and Line2:

I configured the sound device in the device tree file:

sound-myboard {
    compatible = "simple-audio-card";
    simple-audio-card,bitclock-master = <&dailink_master>;
    simple-audio-card,format = "i2s";
    simple-audio-card,frame-master = <&dailink_master>;
    simple-audio-card,mclk-fs = <32>;
    simple-audio-card,name = "myboard";
    simple-audio-card,routing =
        "LINE1L", "Line In",
        "LINE1R", "Line In",
        "Line In", "Mic Bias";
    simple-audio-card,widgets =
        "Line", "Line In";

    dailink_master: simple-audio-card,cpu {
        sound-dai = <&sai2>;
    };

    simple-audio-card,codec {
        sound-dai = <&tlv320aic3109>;
    };
};

I enabled the codec SND_SOC_TLV320AIC3X in the kernel config.

I can see that the device found in the kernel messages:

[ 2.270140] ALSA device list:
[ 2.273127] #0: myboard

But when I try to test the recording with:

arecord -t wav -c 2 -r 44100 -f -d 5 S16_LE /tmp/test.wav

No sound is audible in the file.

amixer outputs the following settings:

Is there some way to debug why there is no sound in my audio file? Thank you for your help.

Add log in the two probe functions in 3109 driver code to check whether both probes have been called.

0 David Schmidt over 1 year ago in reply to Shenghao Ding

It seems both probe functions are called and executed until end:

root [ /tmpfs/root ] $ dmesg | grep aic
[    1.846790]  aic3x_i2c_probe enter
[    1.850696]  aic3x_i2c_probe exit
[    2.145669]  aic3x_probe enter
[    2.148886]  aic3x_probe exit

What's the return value in aic3x_prob? Is your system Linux or Android?

share the tlv320aic3109 define in DTS

The aic3x_probe function executes until the end and returns 0.

I'm on the Linux Freescale kernel 5.10.72.

I have slightly adapted my sound card defintion:

        bitclock-master = <&sound0_master>;
        frame-master = <&sound0_master>;

Still the same problem. Sound card is found during boot, arecord seems to be working but no audio to hear in the recorded sound file.

Kindly measure the I2S clk both bit bck and WS clk with scope and share the waveform.

This is the output for the whole 1 second record:

1-sec-record

The clocks look like this:

Hi Guy

I can not see your clock and 1-sec-record icons

I can't confirm the freq of bck and WS clk. One more thing, dump the register with me. thanks.

Dear Shenghao Ding, I have found the issue:

It was this setting in the i.MX8 SAI interface:

fsl,sai-synchronous-rx;

After removing this setting, sound is correctly recorded.

Thank you for your help!
