Issues with playing song in another thread and then pausing it in the main thread

[cow0075]

Hello
I am trying to have a song play in the background of my app and then pause it whenever I need to. I am probably doing something wrong.
Simplified simulation of what I am trying to achieve:

from audioplayer import AudioPlayer
import threading
import time

a = AudioPlayer(r"D:\songs\bee.mp3")

def test():
    a.play() # 'block=True' here doesn't help with the .pause or .resume issues.

b = threading.Thread(target=test) # Creating a thread
b.start() # This successfully starts the song

time.sleep(10)
print("pausing") # Prints out after 10s
a.pause() # Doesn't affect it at all

time.sleep(10)
print("resuming")# Prints out after another 10s and the program ends

a.resume() # The song just ends here, .resume once again has no effect.

Hi,
I would use threding.Event() to do what you're asking for:

from audioplayer import AudioPlayer
import threading
import time


def background_audio():
    audio_playback_1.play()

    while True:
        if pausing.isSet():
            audio_playback_1.pause()

        if resuming.is_set():
            pausing.clear()
            resuming.clear()
            audio_playback_1.resume()


if __name__ == "__main__":
    audio_playback_1 = AudioPlayer(some_audio_file)
    pausing = threading.Event()
    resuming = threading.Event()
    audio_thread = threading.Thread(target=background_audio)
    audio_thread.start()

    time.sleep(10)
    print("pausing")
    pausing.set()

    time.sleep(10)
    print("resuming")
    resuming.set()

Although i don't think using threads is a good idea, at least on Windows. As of I understood reading the source code, this module is passing commands to the winmm.dll library which provides access to the WinMM API. So you're basically creating threads to run commands to tell the audio player (managed outside of python by windows) to do something.
Note that I may be wrong as I discovered this module 4 hours ago and I don't have any link with its author.
