AudioGenerator should let AudioOutput finish playing buffered samples.
Reproduction:
=> large part of sound file is not played
The common loop:
if (mp3->isRunning()) {
if (!mp3->loop()) mp3->stop();
} else {
Serial.printf("MP3 done\n");
delay(1000);
}
stops AudioOutput as soon as last sample is pushed to output. All buferred samples are discarded.
Solution:
After pushing last sample, AudioGenerator should call AudioOutput->finish() as long as it returns false.
While finishing, AudioGenerator should return true from AudioGenerator->IsRunning() and AudioGenerator->loop().
Implemented for AudioOutputI2S ( and AudioOutputNoDAC effectivelly ) , and AudioGeneratorMP3 and AudioGeneratorWAV.
Other classes work as before ( not affected ).
