How to turn on and off A2DP sink without loosing memory

[dharmikP17]

I am using ESP32 (2.0.5) with Arduino IDE (2.0.2). All settings are default.

My requirement is to turn off the A2DP and start wifi then switch back to A2DP. So I have basic code that just turn on and off the A2DP sink and there is memory leak in heap everytime it goes through this cycle.

#include "BluetoothA2DPSink.h"
#include "BluetoothSerial.h"
BluetoothA2DPSink a2dp_sink;
BluetoothSerial SerialBT;

bool flag_init_serialbt = true;

void connection_state_changed(esp_a2d_connection_state_t state, void *ptr) {
  Serial.println(a2dp_sink.to_str(state));
}

void audio_state_changed(esp_a2d_audio_state_t state, void *ptr) {
  Serial.println(a2dp_sink.to_str(state));
}

void setup() {
  Serial.begin(115200);
  pinMode(2, OUTPUT);
  // a2dp_sink.set_on_connection_state_changed(connection_state_changed);
  // a2dp_sink.set_on_audio_state_changed(audio_state_changed);
  a2dp_sink.start("ESP_A2DP_test", false);
  SerialBT.begin("ESP_A2DP_test");
}
void loop() {
  a2dp_sink.end();
  Serial.print("free heap : ");
  Serial.println(ESP.getFreeHeap());
  delay(3000);
  a2dp_sink.start("ESP_A2DP_test", false);
  delay(3000);
}

There is an option to release memory in a2dp_sink.end(bool release_memory) method but then it will not let me turn on again saying re-start does not work with end(true) .
