Hello：

About Audio codec TLV320AIC3254 application problems:

1.  Audio codec TLV320AIC3254 output 1kHz sin wave, Audio codec 3254 how to control the 1kHz sine wave volume and adjust the volume size? (very important)

2. Audio Codec TLV320AIC3254 output 1kHz sin wave, after amplifier amplification, it will not distortion

    Hi, Leon,

    In order to adjust the sine wave volume, you would need to modify the Page 0 /Register 65-66.

    Could you provide your register configuration, please? This is to have a better approach to this issue.

    Thank you.

    Best regards,

    Hello

    Thank you for your support。

    We are using the TLV320AIC3254 EVM test to adjust the 1kHz sine wave, 3254 output normal.

    But, the use of our design board(monitor) test, Audio codec(3254) is set to 1kHz sin wave mode, audio codec no 1kHz waveform output.

    The following is TI provides audio codec I2C command, please help check.

    For headphone and speaker, we suggest to control the following amp gain setting instead of the volume inside DSP.

    For headphopne control register, it is in page 1 register 16 and page 1 register 17.

    For line out speaker path, it is in page 1 register 18 and page 1 register 19.

    Hi, Zhao,

    The documentation that you attached seems to refer to a PurePath Studio process flow. Could you send me the process flow that you are using? It is a .pfw file that works on PurePath Studio. This is to have a better approach to this issue.

    Thank you.

    Best regards,
    Luis Fernando Rodríguez S.
