TLV320AIC3104: There is no sound when using tinyplay to play a WAV file.

Tool/software:

Hi TI teams,

There is no sound when using tinyplay to play a WAV file.

There is a data signal on the codec DIN. The frequency of MCLK is 11.36 MHz, and the frequency of BCLK is 14.14 MHz.

The i2cdump information is as follows:

tinymix cfg:

Number of controls: 114

    Hi,

    What is your intended sample rate? Is FSYNC being provided as well to the device?

    Thanks,
    Jeff McPherson

    sample rate is 44.1KHz. The main device has FSYNC connected to the codec

    Hi,

    The sound needs to be output to LEFT_LOP/M. How can I configure the reg or kcontrol?

    Hi,

    I would recommend using the AIC310x EVM GUI to configure an I2C script here, but I got the default line out script there and added comments to explain how the DAC and line out outputs are configured. However, one thing to note is that your BCLK/MCLK do not seem to be multiples of 44.1k, so the DAC would not work as expected. According to the clock tree in the datasheet, CODEC_CLK needs to be 256*fs, which for 44.1k as your fs(ref) it will need to be 11.29MHz. CODEC_CLK can be set through CLKDIV_IN, so just make sure either your MCLK or BCLK is 11.2896MHz and then set that clock as the CLKDIV_IN in register 0x66. BCLK does not have to be this high if you are just trying to do stereo I2S at 16 bits for example, BCLK would need to be 44.1kHz * 16 * 2 = 1.4112MHz at a minimum. But, general rule of thumb is that BCLK should always be an integer multiple of the WCLK/sample rate, ideally a factor of 2*16, 20, 24, or 32 as these are standard audio bit depths. 

    # example script from the GUI
# stereo line out playback
w 30 07 8A #44.1k, left dac plays left channel, right dac plays right channel
w 30 66 A0 #clkdiv_in uses bclk, pllclk_in uses bclk -> PLL is disabled by default so this is fine
w 30 25 C0 #l+r dac powered up
w 30 29 02 #volume control is same between left and right
w 30 2B 00 #left dac not muted, gain =0db
w 30 52 80 #dac_l1 routed to left_lop/m, gain=0db
w 30 5C 80 #dac_r1 routed to right_lop/m, gain=0db
w 30 56 09 #output level=0db gain, left_lop/m is NOT muted, left_lop/m fully powered up
w 30 5D 09 #same for right line out

    Let me know if you have more questions about the clocks or the configuration.

    Best,
    Mir
