No sound on Windows and Linux

[Doxo02]

I've been trying around for a little bit now and can't seem to be getting any sound output on either Windows or Linux.
I did try it on an old MacBook where it worked but i can't figure out why it won't on other Platforms.
Has anyone else experienced this?

Hi @Doxo02, could you give some more details.
You are referring to using ALE with render mode human?

[Doxo02]

Hi @pseudo-rnd-thoughts, yes I am referring to the human render mode.
Specifically I've tried this code:

import gymnasium as gym
import ale_py

env = gym.make('ALE/Breakout-v5', render_mode="human")  # remove render_mode in training
obs, info = env.reset()
episode_over = False

env.unwrapped.ale.setBool("sound", True)

while not episode_over:
    action = env.action_space.sample()
    obs, reward, terminated, truncated, info = env.step(action)

    episode_over = terminated or truncated
env.close()

I'll have a look this weekend on my windows and linux desktop to see if I can replicate the issue.

My guess is that SDL2 or Pygame have a problem on those two OSes

I had a look and I can't understand why it doesn't work.
