a2dp spdif not working

[guteSeite]

sorry for the wrong folder. Do you have a working arduino sketch for ESP32 A2DP SPDIF. Your example from 2020 is not working for me. Error because of a missing 2nd parameter (SPDIF output)

[JohnyMielony]

Sketch in example is the working one. Did You use my fork of ESP32-A2DP library? That fork has beed modified to support SPDIF output.

yes I tried this sketch with errors: on arduino 1.8.15:

/Users/bg/Documents/Arduino/libraries/ESP32-A2DP-master/examples/bt_music_receiver_simple/bt_music_receiver_simple.ino: In function 'void setup()': bt_music_receiver_simple:21:28: error: no matching function for call to 'BluetoothA2DPSink::start(const char [8])' a2dp_sink.start("MyMusic");

I don't know how to define PDIFOut *output for working :-(

[JohnyMielony]

I thought You wanted to compile CD changer emulator. Now I see You want A2DP sink with SPDIF output. Try this: `#include "BluetoothA2DPSink.h"

BluetoothA2DPSink a2dp_sink; SPDIFOut *out;

void setup() {

out = new SPDIFOut(); a2dp_sink.start("MyMusic",out);

}

void loop() {}`

I tried compiling, and it did without any errors. I want to mention that You will need additional hardware for SPDIF working. In minimalistic solution it is one capacitor and two resistors forming voltage divider.

wow , now it's working! Thank you so much. I don't need hadware. Just a red LED and a resistor at the ESP32 pionout. Tested with my Yamaha Receiver.

[JohnyMielony]

Yes, for TOSLINK a LED is enough.
