Dear Support Team,
We are interfacing TLV320AIC3204 interfacing with TPA3113D2PWPR in our design and have connected LOL and LOR pins to two TPA3113D2PWPR for stereo confirguration. Attached is the schematic for the same.
We are facing the issue when we play and stop the audio clip, we see a pop noise on the output of the speaker amplifier which is audible in the speaker. Can you please let us know what is the changes required either on the codec side or on the amplifier side to remove this pop noise from our design. We are working to solve this issue from last one month and have tried following options in the design:
1. Changed the value of C141 to 1uF to remove the hiss noise.
2. Changed the status of the C159 and C160 to Do not populate.
3. Changed the value of R221 and R222 to 0E to see if there is any improvement or not.
4. Changed the bit clock of codec from 48KHz to 44.1KHz.
5. Added a 10K pull down resistor on the C142 (AVDD supply).
6. Isolated the speaker amplifier and observed on the audio codec but the pop noise is still there.
7. Changed the Gain setting from the software and tried but still the pop noise is available.
Attached is the schematic, register dump when the codec is idle and when the playback is done on the codec.
If you have any working design in which TLV320AIC3204 is interfaced with TPA3113D2PWPR then please help to share the same. Also, please let us know if we can modify the software to remove this pop noise.
Regards,
Khemraj
