Just got my Raspberry Pi 3 and I'm very excited to learn how to use this!
For context, I'm designing an android mobile app that will have the user press one of four buttons. Each button is mapped to a sound that will play on a specific speaker connected to a raspberry pi.
Right now, I'm in the hardware planning part. What speakers would be suitable for an application like this, and do I have to get an external sound card to support all this? I've looked into solutions like the Adafruit I2S 3W Class D Amplifier Breakout - MAX98357A (https://www.adafruit.com/product/3006) and multiple individual Adafruit USB Audio Adapters (https://www.adafruit.com/product/1475), but I have zero experience with digital/analog audio and I'm hopelessly lost.
Help a noob out?
