TLV320AIC3105: TLV320AIC3105 MIC issue

Hi Luis,

Thanks for your quick response.

I don’t directly configure the codec registers; instead, I use alsamixer to configure audio device. Here is the register map from the driver file tlv320aic3x.c, I believe that kernel uses this map as default configuration.

static const struct reg_default aic3x_reg[] = {

        {   0, 0x00 }, {   1, 0x00 }, {   2, 0x00 }, {   3, 0x10 },

        {   4, 0x04 }, {   5, 0x00 }, {   6, 0x00 }, {   7, 0x00 },

        {   8, 0x00 }, {   9, 0x00 }, {  10, 0x00 }, {  11, 0x01 },

        {  12, 0x00 }, {  13, 0x00 }, {  14, 0x00 }, {  15, 0x80 },

        {  16, 0x80 }, {  17, 0xff }, {  18, 0xff }, {  19, 0x78 },

        {  20, 0x78 }, {  21, 0x78 }, {  22, 0x78 }, {  23, 0x78 },

        {  24, 0x78 }, {  25, 0x00 }, {  26, 0x00 }, {  27, 0xfe },

        {  28, 0x00 }, {  29, 0x00 }, {  30, 0xfe }, {  31, 0x00 },

        {  32, 0x18 }, {  33, 0x18 }, {  34, 0x00 }, {  35, 0x00 },

        {  36, 0x00 }, {  37, 0x00 }, {  38, 0x00 }, {  39, 0x00 },

        {  40, 0x00 }, {  41, 0x00 }, {  42, 0x00 }, {  43, 0x80 },

        {  44, 0x80 }, {  45, 0x00 }, {  46, 0x00 }, {  47, 0x00 },

        {  48, 0x00 }, {  49, 0x00 }, {  50, 0x00 }, {  51, 0x04 },

        {  52, 0x00 }, {  53, 0x00 }, {  54, 0x00 }, {  55, 0x00 },

        {  56, 0x00 }, {  57, 0x00 }, {  58, 0x04 }, {  59, 0x00 },

        {  60, 0x00 }, {  61, 0x00 }, {  62, 0x00 }, {  63, 0x00 },

        {  64, 0x00 }, {  65, 0x04 }, {  66, 0x00 }, {  67, 0x00 },

        {  68, 0x00 }, {  69, 0x00 }, {  70, 0x00 }, {  71, 0x00 },

        {  72, 0x04 }, {  73, 0x00 }, {  74, 0x00 }, {  75, 0x00 },

        {  76, 0x00 }, {  77, 0x00 }, {  78, 0x00 }, {  79, 0x00 },

        {  80, 0x00 }, {  81, 0x00 }, {  82, 0x00 }, {  83, 0x00 },

        {  84, 0x00 }, {  85, 0x00 }, {  86, 0x00 }, {  87, 0x00 },

        {  88, 0x00 }, {  89, 0x00 }, {  90, 0x00 }, {  91, 0x00 },

        {  92, 0x00 }, {  93, 0x00 }, {  94, 0x00 }, {  95, 0x00 },

        {  96, 0x00 }, {  97, 0x00 }, {  98, 0x00 }, {  99, 0x00 },

        { 100, 0x00 }, { 101, 0x00 }, { 102, 0x02 }, { 103, 0x00 },

        { 104, 0x00 }, { 105, 0x00 }, { 106, 0x00 }, { 107, 0x00 },

        { 108, 0x00 }, { 109, 0x00 },

};

I am not sure if the driver tlv320aic3x.c fully supports tlv320aic3105, for instance, support recording.

Hi Luis,

In our application, MIC1L/LINE1L is the input connected to left PGA and left ADC, the register 15 and register 19 of the page 0 need to be configured. When the codec tlv320aic3105 is brought up, these two registers are set from TI driver aic3x_init() as following:

After the codec is up running, I run alsamixer to configure PGA Capture, below is the copy of ADC config changes:

        control.44 {

                iface MIXER

                name 'PGA Capture Volume'

                value.0 119

                value.1 119

                comment {

                        access 'read write'

                        type INTEGER

                        count 2

                        range '0 - 119'

                        dbmin 0

                        dbmax 5950

                        dbvalue.0 5950

                        dbvalue.1 5950

                }

        }

        control.45 {

                iface MIXER

                name 'PGA Capture Switch'

                value.0 true

                value.1 true

                comment {

                        access 'read write'

                        type BOOLEAN

                        count 2

                }

        }

However, when I run the capture, I see the error

arecord: pcm_read:2031: read error: Input/output error

I don't know what causes this error.

I also compare tlv320aic3105 register map, the register 73-79 of page 0 in tlv320aic3105 are reserved,  not sure if writing the values to these registers has any impact, which is done in aic3x_init().

Best regards,

Bruce

Hi Luis,

Thanks for your help, I will try.

Best regards,

Bruce

Hi Luis,

Tlv320aic3105 capture is still not working, it hangs when running capturing. We checked that Page 0/ Register 19 and Register 22, Bit D2 is 1 when doing recording, the values of Page 0 /Register 15 and 16 are 0x77.

We made some changes on da830_evm_dai  and evm_dai_tlv320aic3x  in davinci-evm.c,

1. change .cpu_dai_name and .platform_name from "davinci-mcasp.1" to  "davinci-mcasp.0" to support both playback and capture;
2. change .dai_fmt to I2S.

tlv320aic3105 provides bit clock and frame clock.

Below are changes:

static struct snd_soc_dai_link da830_evm_dai = {

        .name = "TLV320AIC3X",

        .stream_name = "AIC3X",

        .cpu_dai_name = "davinci-mcasp.0",

        .codec_dai_name = "tlv320aic3x-hifi",

        .codec_name = "tlv320aic3x-codec.1-0018",

        .platform_name = "davinci-mcasp.0",

        .init = evm_aic3x_init,

        .ops = &evm_ops,

        .dai_fmt = SND_SOC_DAIFMT_I2S | SND_SOC_DAIFMT_CBM_CFM |

                   SND_SOC_DAIFMT_NB_NF,

};

……

static struct snd_soc_dai_link evm_dai_tlv320aic3x = {

        .name           = "TLV320AIC3X",

        .stream_name    = "AIC3X",

        .codec_dai_name = "tlv320aic3x-hifi",

        .ops            = &evm_ops,

        .init           = evm_aic3x_init,

        .dai_fmt = SND_SOC_DAIFMT_I2S | SND_SOC_DAIFMT_CBM_CFM |

                   SND_SOC_DAIFMT_NB_NF,

};

I am not sure if these changes are correct or I need to make some other changes as well.

Best regards,

Bruce

Hi Luis,

I managed to get the tlv320aic3105 capture up running, but it captures the noise. The codec configuration is:

1. Codec is configured as slave, which the host provides bit clock and frame clock;
2. TX and RX work on synchronous mode, which host provide only TX bit clock and frame clock to tlv320aic3105;
3. MiC1L/LINE1L is selected as audio input.

Register dump of tlv320aic3105 is as following:

Please help me understand the issue.

Hi Bruce,

i'm using TLV320AIC3105 on my iMX6 board, i use codec driver tlv320aic3x.c and machine driver imx-tlv320aic3x.c.

when kernel running, it shows:

imx-tlv320aic3x sound: tlv320aic3x-hifi <-> 202c000.ssi mapping ok

....

ALSA device list:
 #0: tlv320-audio

and I2C communication is working well (i can read/write registrer of codec ic)

but when i play music, i don't see BCLK, WCLK, I2S data out (TXD), only have MCLK (24MHz) and of cause, no sound! 

i spend one week to find what is problem but not success!

Can you share me your codec driver and machine driver?

Many thanks!

BR/Hai

Hi Hai,

TI audio codec driver tlv320aic3x works for tlv320aic3105 if you run playback.

Regards,

Bruce

Hi Bruce,

i see there are two drivers: tlv320aic3x.c (Author: Vladimir Barinov) and tlv320aic31xx.c (Author: Jyri Sarha <jsarha@ti.com>)

i use tlv320aic3x.c but not success, which driver did you use?

Please help me, now i'm really stuck!

Thanks!

Regards,

Hai 

I use tlv320aic3x.c.  

Hi Bruce,

i can make clock out on SSI WCLK, BCLK and Data out line. But i measure on RIGHT_LOM, RIGHT_LOP, LEFT_LOM, LEFT_LOP, HPLOUT, HPROUT... of TLV320AIC3105 ic, no anyone has data clock out, and no sound!

in device tree, i use audio-routing:

"Ext Spk", "LLOUT",

"Ext Spk", "RLOUT",

"Line Out Jack", "LLOUT",

"Line Out Jack", "RLOUT",

"Headphone Jack", "HPLOUT",

"Headphone Jack", "HPROUT";

Can you share me audio-routing in your device tree?

Thanks!

Regards/Hai

Hi Hai,

Here is device tree I used

"Headphone Jack", "HPLOUT",
"Headphone Jack", "HPROUT",
"LINE1L", "Line In",
"LINE1R", "Line In";

Regards,

Bruce

Hi Hai,

Did you capture the sound from TLV320aic3105 MIC? Do you use RX clock or share TX clock? Is tlv320aicaic3105 master mode or slave mode? Which port do you use, MIC1L/Line1L or other port?

Best regards.

Bruce

Hi Bruce,

i can capture from TLV320AIC3105 using MIC1L/LINE2L/LINE2R input, the quality of record sound is acceptable, not much noise.

I'm using external MCLK from master MCU,  TLV is in slave mode.

My diagram:

Master MCU  ----- TLV codec

CLK_OUT (24MHz) --> MCLK

AUD3_TXD     -    I2S_DIN

AUD3_RXD    -    I2S_DOUT

AUD3_TXFS  -    I2S_WCLK

AUD3_TXC    -    I2S_BLCK

Hai
