Audio Output from ESP32 LyraT Phone Jack is not clear

[Srikanth]

Hello!

I have recently bought ESP32 LyraT V4.3.
I am executing pipeline_sdcard_mp3 example in ESP32 ADF SDK. pipeline_sdcard_mp3 application uses the default configuration of I2S and mp3 decoder.

I have observed that quality of the audio output from Phone Jack is not clear. How do I get a clear audio output ?
Please update me on this issue.
