Linux/AM5728: AUDIO codec TLV320AIC3106 support

Part Number: AM5728
Other Parts Discussed in Thread: TLV320AIC3106, BEAGLEBOARD-X15, DRA72

Tool/software: Linux

hi,

we designed our custom board with AM5728 and it has interface with audio codec TLV320AIC3106.

we are providing clk to codec from external CXO not from processor.

The dtb definitions are  below  and we got the following eroors in boot logs.

sound0: sound@0 {
        compatible = "simple-audio-card";
        simple-audio-card,name = "BeagleBoard-X15";
        simple-audio-card,widgets =
            "Line", "Line Out",
            "Line", "Line In";
        simple-audio-card,routing =
            "Line Out",    "LLOUT",
            "Line Out",    "RLOUT",
            "MIC2L",    "Line In",
            "MIC2R",    "Line In";
        simple-audio-card,format = "dsp_b";
        simple-audio-card,bitclock-master = <&sound0_master>;
        simple-audio-card,frame-master = <&sound0_master>;
        simple-audio-card,bitclock-inversion;

        simple-audio-card,cpu {
            sound-dai = <&mcasp8>;
        };

        sound0_master: simple-audio-card,codec {
            sound-dai = <&tlv320aic3106>;
        };
    };

&i2c2 {

    status = "okay";
    clock-frequency = <400000>;

    tlv320aic3106: tlv320aic3106@18 {
        #sound-dai-cells = <0>;
        compatible = "ti,tlv320aic3106";
        reg = <0x18>;
        status = "okay";

        AVDD-supply = <&vdd_3v3>;
        IOVDD-supply = <&vdd_3v3>;
        DRVDD-supply = <&vdd_3v3>;
        DVDD-supply = <&aic_dvdd>;
    
    };

};

&mcasp8 {
    #sound-dai-cells = <0>;
    status = "okay";

    op-mode = <0>;    /* MCASP_IIS_MODE */
    tdm-slots = <2>;
    /* 4 serializers */
    /* 0: INACTIVE, 1: TX, 2: RX */
    serial-dir = <    
        1 2 0 0
    >;
    tx-num-evt = <32>;
    rx-num-evt = <32>;
};



No sounds cards found
asoc-simple-card sound@0 :cannot find the slot for index 0 (range 0-0) ,error: -16
asoc-simple-card sound@0 : can't create sound card for card BeagleBoard-X15: -16
asoc-simple-card sound@0 : probe of sound@0 failed with error -16

Kindly help.

  • Hi Satyanarayana,

    Do you use AM57x PSDK Linux v5.02 (kernel v4.14.79)? Did you made any changes in the audio driver files or the only changes are in DTS file?

    Can you provide the full boot up log?

    Regards,
    Pavel

      hi Pavel,

    We are using sdk 03.02 linux kernel 4.4.32 .

    We have not modified driver files. Changes are only in dts files.the boot log is attached.

    we are providing clock from external source to codec MCLK.

    how to define and handle this please suggest.

    BR

    satya

  • Hi Pavel,

    please provide the support as early as possible.

    what and all modifications to done for input of MCLK through external clock to access audio codec.

    we are following the EVM schematic except the clock to MCLK pin from external osc.

    BR
    satya
  • Satya,

    Can you make the below DTS update and try with it, will be there any improvement?

    - sound0: sound@0 {
    + sound0: sound0 {


    sound0_master: simple-audio-card,codec {
    sound-dai = <&tlv320aic3106>;
    + system-clock-frequency = <24500000>;
    };

    Note that AM335x TI EVM is using similar approach as in your custom board. AM335x TI EVM is using AIC3106 codec and 12MHz external clock source for the codec MCLK input. So you can refer to AM335x TI EVM DTS file for reference - am335x-evm.dts

    Make sure also your DTS file is aligned with below doc files:

    linux-kernel/Documentation/devicetree/bindings/sound/simple-card.txt
    linux-kernel/Documentation/devicetree/bindings/sound/tlv320aic3x.txt
    linux-kernel/Documentation/devicetree/bindings/sound/davinci-mcasp-audio.txt

    Regards,
    Pavel
  • Hi Pavel,

    we made changes
    sound0_master: simple-audio-card,codec {
    sound-dai = <&tlv320aic3106>;
    + system-clock-frequency = <24500000>;

    audio codec is detected and we captured the audio but we didnt hear anything but it is recorded.

    what to do

    BR
    satya
  • Satya,

    Please provide the latest console boot up log plus arecord command execution for analysis.

    Check also if below doc will be in help:

  • hi pavel,

    we are able to record single tone frequencies and multiple frequencies, but we are not able to hear music or voice when we play audio file.

    BR
    satya
  • Satya,

    How exactly you record and then play audio? Do you use arecord then aplay tools? Or do you use record and playback applications? Please provide me console log of your record and play procedure.

    Make sure you are checking the steps from below section of the doc I have provided:

    www.ti.com/.../sprac10.pdf

    6.4 Audio Playback is Muted

    Make sure also you are aligned with below user guide:

    software-dl.ti.com/.../Foundational_Components_Kernel_Drivers.html

    Regards,
    Pavel
  • Hi,

    Can you answer few queries on codec.
    1. What is the min and max analog voltage for codec can sustain ( i.e sensitivity level and withstand level).
    2. Can I use single line 2L or 2R as one audio input as for recording.
    3. If I configure line 2L as stereo, is it necessary to connect line 2R for recording.
    4. In my requirement I have only one audio input, but tapped to Line 2L and 2R for redundancy. For recording how to handle this to capture audio of level range from micro volts to 200mV on both lines 2L and 2R. Recorded using gstreamer and store in memory during playback it plays only single tone frequency not speech file or audio music file.
    Any AGC or PGA settings required to do so please suggest.

    BR

  • Hi,

    Sure, I will open new thread in audio forum.
    Today we have recorded audio using arecord instead of gstreamer. The outcome for an input of single tone p-p signal is positive signal with negative signal clipped and samples are dropped enormously.
    Please suggest what configuration has to be done to avoid negative clipping and without dropping samples.

    BR
    Satya
  • Satya,

    Is this the same issue as reported in the below new e2e thread?

    e2e.ti.com/.../775311

    If yes, please close/verify/resolve this one and we will continue with the new thread.

    Regards,
    Pavel
  • hi,
    yes it is, he is our sw guy. since i'm not getting proper response he opened a thread to discuss from SW view.
    In my hardware point of view, i have supplied single ended input of range 600mV rms (300mV peak).
    the output is captured in the processor and when view the spectrum of recorded output in audacity sw. it is like half wave rectifier output of input sinewave.
    for a single tone input , the output is tone along with harmonics and it is ok to hear the tone.
    when we increase the volume the signal is clipped on top. when we decrease the volume to 100mV there is no output.

    For a audio file input, we are getting only noise and in spectrum with dropped samples.

  • hi,

    we are able to record single tone frequency without any issue, when we play audio file we are not able to hear anything except hss sound.

    now, guide us what to do to hear audio file.

    we will debug step by step as per your guidelines, our main aim to hear voice from our codec through digital data not from DAC.

    Br
    satya
  • Satya,

    I will suggest you to attach a scope to the AM57x McASP data out pin and check if it has valid and expected signal. If you have AM57x EVM, you can use its McASP data out pin to compare how the signal should behave on that pin.

    Thus you will isolate the issue, you will determine if the issue is in AM57x MCASP module or in AIC3106 audio codec. If the issue is in AM57x McASP module, we can dump the McASP registers and check the values there. If the issue is in AIC3106 audio codec, you need to ask/post in the Audio forum, as I can not advice regarding AIC3106 codec settings.

    If you can provide the console output of your aplay execution, that might be also in help.

    You also have these two messages in your kernel log, you might investigate why they appear and how to fix:

    of_get_named_gpiod_flags: can't parse 'simple-audio-card,hp-det-gpio' property of node '/sound@0[0]'
    of_get_named_gpiod_flags: can't parse 'simple-audio-card,mic-det-gpio' property of node '/sound@0[0]'

  • Satya,

    I am able to play wav file on AM572x TI EVM and hear the sound successful. I am using headset pluged in P8 (Audio out) jack. When I boot up the EVM, I am executing below commands as suggested by the user guide:

    amixer -c BeagleBoardX15 sset PCM 90

    amixer -c BeagleBoardX15 sset 'Left Line Mixer DACL1' on

    amixer -c BeagleBoardX15 sset 'Right Line Mixer DACR1' on

    amixer -c BeagleBoardX15 sset 'Line DAC' 90

    For boards with AIC3106 codecs, I see we have similar settings, check K2G EVM, AM437x-GP-EVM, DRA7 and DRA72 EVM, AM335x EVM, AM335x EVM-SK

    I am attaching the full kernel boot log plus aplay execution for your reference:

    https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/791/aplay_5F00_AM57x_5F00_EVM

    Please align as much as you can to these steps for your custom board.

    Regards,
    Pavel

  • hi pavel,

    we dont need DAC output, we are processing in AM5728 thru Din of audio codec to mcasp8_axr0.

    we are recording the audio into wav file and storing it into memory drive and playing back in laptop.

    Audio is not clear with dropping of samples for audio voice input file.

    audio is ok, for single tone frequency.

    Regards,
    satya
  • Satya,

    Let me clarify. You are recording audio (with arecord tool) on your AM57x custom board and you get wav file as result. Then you play this wav file with your laptop (not with AM57x custom board) and you do not hear this wav file well. Is that correct?

    Can you share the console log of your arecord command execution?

    Regards,
    Pavel
  • Hi,

    yes it is, the same way I'm doing.

    The problem is resolved when we remove the resistor connected to gnd in line2l-.

    My question is what value of gain to be allowed. right now with 0db is fine , but provision is there for 59.5db.

    what should be the min and max voltage at line2l+ pin. currently we fed at 250mV.

    please advise about the settings.
