Problem Description

When trying to use example "SPIFFS_AMR_RESAMPLE_EXAMPLE" from isp-idf i see error in Serial:
E (16565) I2S: register I2S object to platform failed.
That happen when program try to "Create audio elements for playback pipeline"
But in example log i see: I2S: I2S driver already installed
Searching of this phrase in ADF did not give anything.
Same phrase found in logs of different examples on github.
How to make it work?

Expected Behavior

Working example

Steps to Reproduce

Try to compile any example that use 2 channels at once

[Jon811]

In another hand when i try VoIP example i have the same error message and it's not working, so i think it will happen in any example containing both speaker and mic.

[hbler99]

No worries, this is normal for IDF v4.4 and does not affect your work.

[Jon811]

If it doesn't affect, then it's just not working. How to make it work in VSCode? May be there some example menuconfig, that works from someone?

[Jon811]

Here is recording:
I (8305) SPIFFS_AMR_RESAMPLE_EXAMPLE: Setup file path to save recorded audio
I (12695) SPIFFS_AMR_RESAMPLE_EXAMPLE: STOP recording and START playback
4 seconds, and here is playback:
I (12765) SPIFFS_AMR_RESAMPLE_EXAMPLE: Setup file path to read the amr audio to play
W (12785) SPIFFS_STREAM: No more data, ret:0
20 milliseconds. So it's not work.
