TAS2110: I2S clocks

TJ

Part Number: TAS2110

My customer is using this driver https://git.ti.com/cgit/tas256xsw-android/tas2562-android-driver/ and seeing an issue where sometimes when the I2S clocks are stopped and restarted quickly in succession, the chip is staying in its software shutdown mode instead of being put back into the active mode. I was wondering if you had any idea of how to prevent this?

    Seeing if anyone is assigned to this question?

    Hi TJ,

    Sorry for late response, it is most likely the device is triggering clock error flag and shutting down.
    Do you have control on when the clocks are stopped and reinitiated? If possible you should set the device into software shutdown mode, stop the clocks and once the clocks are back up take the device into active mode again.
    If you cannot do that, there may be a feature to auto-enable the device when it detects the clocks, let me double check if this feature is available in TAS2110.

    Hi Ivan,

    I've passed that along. Have you been able to find out if there's an auto-enable feature?

    Hi TJ,

    Couldn't find auto-enable mention on this one, perhaps it's only available on DSP featured devices.

    However you may try to set register 0x30 bit 6 = 1. This would disable the auto-mute when detecting clock error, although you should test this to double check audio is not getting noisy after the clock stops and restarts.
