Working with audio generates error (WSL2 - Windows11)

[toxfu]

only pygame-ce enviroment on WSL (Windows 11)

• Operating system (Linux(Ubuntu) WSL2):
• Python version (3.11.9) :
• sdl2 2.30.2
• sdl2_image 2.8.2
• sdl2_mixer 2.6.3
• sdl2_ttf 2.22.0
• pygame-ce version (2.4.0.1):

when I want to work with audio, regardless of the code, it always generates the following error:

ALSA lib confmisc.c:855:(parse_card) cannot find card '0'
ALSA lib conf.c:5204:(_snd_config_evaluate) function snd_func_card_inum returned error: No such file or directory

I have already tried the solution with PulseAudio, it works well with applications. But I can't get it to work with pygame.

postscript: I have used this tutorial https://www.linuxuprising.com/2021/03/how-to-get-sound-pulseaudio-to-work-on.html

It seems like pygame-ce is trying to find PulseAudio and failing, then falling back to using ALSA.

Could you try updating to pygame-ce 2.5.0.dev2 and using the PipeWire driver? To use the pipewire driver just do something like SDL_AUDIODRIVER=pipewire python3 your_app.py

As I had been working with my WSL environment for years, at the time the audio was a problem, so I did the pulseaudio tutorial.

Searching I found that WSL now comes with WSLg (which has audio control included). Installed a new WSL environment and everything works great with audio (includes pygame-ce=2.4.1).

Thanks for your time.
