Sound Options through RP4

Working on a hockey siren project that activates a rotating beacon if a selected hockey team scores. Curious of the best option to play custom audio (e.g. horn sounds, goal music, etc.) through a RP4. I have an 8ohm speaker & LM386 chip, but now I'm thinking that can only be used to process the most basic of sounds through PWM (am I wrong?). Trying to not send the audio over bluetooth to a speaker to avoid having an additional peripheral (which decreases portability of the device). Any other options y'all can think of?

Pi4 has full blown soundcard that can easily play music.

Works as any other computer soundcard <@267468714486530058>

You can use hdmi out for digital audio output as well.

Pi4 is often used as mediaplayer for movies 🙂

I founf the easy way to play a .wav soundfile is to use Pygame: import pygame # initialize pygame mixer pygame.mixer.init() # load sound file sound = pygame.mixer.Sound("/path/to/soundfile.wav") # play sound file sound.play() # wait for sound to finish playing while pygame.mixer.get_busy(): pass # cleanup pygame mixer pygame.mixer.quit()

pip install pygame 😉

yep

This is helpful..thank you! I've played around with pygame a bit so am comfortable there. Any recos on the hardware device to play audio? Could I play it through the PWM ping to one of those small 8ohm speakers? Any small devices that could mount inside a small housing with the rotating beacon that I could use the hdmi audio out with?

<@267468714486530058> why dont you just use that 3.5mm jack on your pi for audio out?
