Hi Ti team，

When implementing Stereo 2.0 audio output with the TAS5825M in the new project, distortion occurs when the input sampling rate is 192kHz. Comprehensive tests have been conducted using the settings marked by the red box in the graphical user interface (GUI).Could you please help analyze the reasons?

Hey ,

Please give more information on the distortion observed. What type of distortion? clipping ? noise ? How does this affect the output signal or audio performance parameters you've observed?

Regards,

Ore.

It has been resolved.Thank you for your support.

We encountered another problem.When we switch the input sampling rate, there will be a POP sound. Is there any way to solve this problem?

Hey,

Is this switch to a different sampling rate done while device is on or is this desired sampling rate configured when the device is being initialized?

Ore.

Hi Ore，

Thank you for your support.

Switch different sampling rates after the TAS5825M is initialized.

Hey,

Discontinuity in signal transmission due to an I2C write would result in noise when device is programmed. Checkout sec 7.6 for timing requirements.

Ore.
