Hi TI-team

My customer want to reduce noise silent cound state.

Is there any way other than lowering the volume ?

Noise means signal noise and sound noise.

Hi, Hayashi-san,

Could you provide more details about this? Could you share the circuit schematic and the current registers configuration that the customer is using?

Additionally, do you have details or scope captures of the noise level that the customer is getting in his application?

Best regards,

Hi TI-team

I heard Luis-san will be out of the office these days.

Can anyone else answer this question ?

Schematics and waveforms cannot be posted to E2E, but can be sent separately.
