VS1053 ESP32 Microphone or Line Input no data available (streams-vs1053-serial.ino)

[pbrownpb18]

I am using the example at the link below, and am not able to get data from line or microphone audio sources.
https://github.com/pschatzmann/arduino-audio-tools/blob/main/examples/examples-vs1053/streams-vs1053-serial/streams-vs1053-serial.ino
I have turned on full Debug. Once the copying starts, I see

[D] AudioOutput.h : 152 - bool audio_tools::CsvOutput<T>::begin(int) [with T = short int]
[D] StreamCopy.h : 115 - copy 1024 bytes 
[D] VS1053Stream.h : 277 - arduino_vs1053::VS1053& audio_tools::VS1053Stream::getVS1053()
[I] VS1053Stream.h : 303 - available: 0
[D] StreamCopy.h : 267 - available: 0
[D] StreamCopy.h : 202 - no data 
[D] StreamCopy.h : 115 - copy 1024 bytes 
[D] VS1053Stream.h : 277 - arduino_vs1053::VS1053& audio_tools::VS1053Stream::getVS1053()
[I] VS1053Stream.h : 303 - available: 0
[D] StreamCopy.h : 267 - available: 0
[D] StreamCopy.h : 202 - no data 

and so on, forever. The full log is available if helpful. I'm using a generic VS1053 board and a standard ESP32 board, as shown in the attached.

I've followed through the code and compared it to other examples and can't find anything obvious.
Any help or hints would be appreciated. My next step would be to log all the register writes during setup.
Thanks

Use the logger of the VS1053 library to figure out what's going on:
Double check that the begin_input_vs1053 is called and that the user code is loaded.

[pschatzmann]

The input functionality was not activated in VS1053Config.h for https://github.com/pschatzmann/arduino-vs1053
Therefore in.begin() was returning false !

I committed a correction to have it activated by default.

Thank you! Busy day today, but I will give this a try as soon as I can.
Yes, I should have checked the return from in.begin(). I'll ensure I check all returns.

Thank you, logging data!
