Hi,

I try to access my audio driver via the below command:
test_audio.py

import pygame
file = '1.wav'
pygame.init()
pygame.mixer.init()
pygame.mixer.music.load(file)
pygame.mixer.music.play()

I could use the above code in the terminal when I am not access the container, but after accessing the container, I could not play it.

The error that I received was:
pygame.error(): no audio driver

Solution which I tested:

import os
os.environ['SDL_AUDIODRIVER'] = 'dsp'

cat /proc/asound/cards

The above code could not work too but it work when I try it on the terminal without accessing the container

Hi,

You will need to mount the nodes to get access within the container.
Could you check the below topic for information first?

Thanks.

Could you play the wav file inside the container with aplay?
Thanks.
