AudioOutput channels remains at value 2

[PascaL-IT]

Cannot set AudioOutput channels at value 1

Test program:

from kivy.core.audio import SoundLoader from audiostream import get_output sound = SoundLoader.load('sounds/kit1/clap.wav') if sound: print("Sound found at %s" % sound.source) print("Sound is %.3f seconds" % sound.length) sound.play() stream = get_output(channels=1, rate=44100, buffersize=1024) print(type(stream))

Output:

Sound found at C:...\sounds\kit1\clap.wav Sound is 0.522 seconds AudioOutput ask for 44100 1 AudioOutput got 44100 2

if stream = get_output(channels=1, rate=22050, buffersize=512) then AudioOutput ask for 22050 1 AudioOutput got 22050 2

Hi, same problem here on windows 10, kivy2.0.0, it's doing a speedy sound for me.

Thanks to helping us

Same problem, For a long time I had exactly the same error (2 channels) and then suddenly I even get 8 channels. So the number of channels allowed can change, over time (not during execution, on different run() ), surprising, isn't it ?
