Need help with audio modules

[vsumpi]

Hi, my project needs audio not High-definition but a loudspeaker or buzzer with a low/high frequency. Do you have any board or USB recommendations? I will need an amp too for 4-amp 2-watt speakers. the panel occupies almost the whole GPIO output so my only choice for a Rpi4 is USB.

in your command, you can use --led-hardware-no-pulse, then you have no need to disable the sound in your Raspberry Pi 3 from the boot. I use the sound, a speaker with amp plugged in the audio of my Rpi 3, and works great

amp plugged in the audio

Is it a 3.5mm jack or USB?

[davemaster]

It is the 3.5mm jack in a RPi 3 B+

For the RPi 5, I use an USB sound board, let me search what model (cheap) and I'll let You know...
