TLV320AIC3100: no playback from speaker

Other Parts Discussed in Thread: TLV320AIC3100

Hi, I am trying to interface a TLV320AIC3100 to an iMx6, and despite all of the registers and signal seem fine, I have no sound coming out from the speaker.

I have printed out all of the registers on page 0 and page 1 -taken via regmap tracing- at the start of a tinyplay; the printout is in the attached text file

I am using a MCLK coming from the iMx6 @ 11'289'600Hz so I added this entry to the aic31xx_divs table: {11289600, 44100, 1, 7, 5000, 128, 3, 5, 128, 3, 5, 4}.

The machine driver, the codec driver, the ALSA layer, they seem all OK, no error messages during initialization.

I checked the signals BCLK/WCLK/DIN/DOUT/SCL/SDA using an oscilloscope and they seem OK too, i.e. I see clock-like signal on WCLK and BCLK, I see data entering the codec I2S and exiting from the codec I2s too.

The SPKP/SPKM signal seem kind of a PWM @ about 350kHz but I hear no sound from the speaker!

Can you help me giving a look to the register settings?

Have you any other suggestion?

Hi, Michele,

I've asked my colleague to work with you on this issue.

Thanks Don,

today I tried to use a different value for MCLK: I used a MCLK frequency of 18857142, which is giving the 44.1kHz WCLK frequency with the setup on div table;
{11289600, 44100, 1, 4, 7895, 128, 2, 8, 128, 3, 5, 4},

I left the first entry to 11'289'600 because this way the system soc core checks fine that MCLK_in_table=44100*256, but in effect the PLL generates about 90MHz clock then scaled down to 44.1KHz.

I checked thw WCLK with an oscilloscope and it has a 44.1kHz frequency which is fine.

The SPK is instead a PWM signal @ about 350 kHz, with duty cycle fixed @ 50% so I suspect there is something wrong maybe with the volume setup... but the signals routing and the volume settings they seem good to me; I tried different values but never got the PWM duty changing from 50%

Sorry for bother you again: I add that with the following mixer setup, I can hear the BEEP, and the PWM changes its duty cycle, so the hardware seem fine
