QSound play old file

[kskim]

python 3.6 / pyside2

my code:

player = QSound('./temp/play.wav')
player.play()
while not player.isFinished():
    QApplication.processEvents()
    time.sleep(0.1)
player.stop()
os.remove('./temp/play.wav')

in my program, receive an audio file with the name './temp/play.wav'. and play it.
but sometimes it play old file.

is it possible that Qsound object is not recreated and the old object is referenced?

I check audio file received from server but it's okay.
there is no problem with path and file downloaded from server.
Additionally, this issue appears intermittently.

@kskim please provide a minimal and reproducible example

[kskim]

def download_audio(audio_path):
    # download audio file from audio-file-server
    with open('./temp/play.wav', 'wb') as f:
        f.write(audio_data)

class myapp:
    def play_audio():
        player = QSound('./temp/play.wav')
        player.play()
        while not player.isFinished():
            QApplication.processEvents()
            time.sleep(0.1)
        player.stop()
        os.remove('./temp/play.wav')

when downloading an audio file from audio-file-server and playing it,
even if I request and download another audio file and then play it, the first file is played.
but the first file is already deleted.

@kskim

player = QSound('./temp/play.wav')
...
os.remove('./temp/play.wav')

One thought is that it may not be a good idea to try to remove the file when you still have an instance of QSound() active on it. I would eliminate that by moving the deletion out of play_audio(), so it has a chance to be freed. In any case, it should not be the job of a function playing an audio file to delete that file. E.g. move the os.remove('./temp/play.wav') into download_audio() before the with open('./temp/play.wav', 'wb') as f:.

Otherwise verify 100% that the audio_data buffer contains different bytes second time around.

Otherwise each time round create and play play1.wav, play2.wav, play3.wav, ... instead of the same filename. Then you will know whether it's an issue about reusing a filename or not.
