TAS2505: Click/pop up noise when playing audio using TAS2505 DAC

Adavappa R2

Part Number: TAS2505

Hi ,

I am facing the issue with click noise when we are playing wav file at 22khz frequency.

I am using the ALSA API's to play the audio.

Is there software solution to fix the noise issue.

ALSA api used to write data on the PCM device is snd_pcm_writei()

Hi, Adavappa,

Could you provide the information below in order to have a better approach to this issue?

- TAS2505 schematic portion.

- Registers configuration.

- Clocks (MCLK, BCLK, WCLK) frequencies.

- Description of the moment when the click noise appears (beginning/end/all moment of the playback),

Best regards,
