Lyratd MSC 2.2 "pipeline_recording_to_sdcard" sound noise (AUD-4435)

[jinyz05]

1. adf master, idf v4.4
2. menuconfig with lyratd msc 2.2 and wav encoder
3. the rec.wav recorded about 1.7MB size
4. fetch and play the wav from sdcard, i got noise sound;

update with latest firmware using "tw_upload_dsp_firmware(-1)", the wav file sound better, but also get noise;

[jinyz05]

[update] speech-recognition demo got no response; player mp3 demo works, but the volume is too low;

[yujonglee]

I am experiencing the exact same problem. Did you find the solution? @jinyz05

[MikeTolkachev]

I am experiencing the exact same problem with volume. I found strange behaviour. If you run the example mp3 player and then disconnect and reconnect one connector between boards A and B, then the sound volume will be high. After pressing the reset button, the sound will become quiet again. Connector image: https://ibb.co/0DDnBHT
