Python winsound, ASYNC flag not working?

问题

I'm using python 3.5 and I'm trying to play a sound while continuing right away with my script; according to https://docs.python.org/3.5/library/winsound.html the flag "winsound.SND_ASYNC" should be the way to go. However the following doesn't produce any sound:

import winsound
winsound.PlaySound('C:/Users/Bob/Sounds/sound.wav', winsound.SND_ASYNC)

Interesting enough if I change the flag to "winsound.SND_FILENAME the sound is played:

import winsound
winsound.PlaySound('C:/Users/Bob/Sounds/sound.wav', winsound.SND_FILENAME)

Any ideas why the async flag doesn't work?

回答1:

According to the docs,

The sound parameter may be a filename, audio data as a string, or None. Its interpretation depends on the value of flags, which can be a bitwise ORed combination of the constants described below

Something like follows:

import winsound
winsound.PlaySound('C:/Users/Bob/Sounds/sound.wav', winsound.SND_FILENAME | winsound.SND_ASYNC)
