Mini External USB Stereo Speaker

Adding this USB-powered speaker to your Raspberry Pi is one of the easiest ways to play great audio out of your project. It's also an ideal affordable speaker option for your Raspberry Pi 400! With just a single USB connection with no other cables, power supplies or any charging required, it's the easiest and most compact audio option for your Raspberry Pi. The unit has two speakers inside and is powered by a single Raspberry Pi USB port. Setup & Usage Since some very recent Raspberry Pi OS changes, we've found that installing Pulse Audio (Raspberry Pi's preferred sound server) helps to get these USB speakers working properly. First, update your Raspberry Pi. In a new terminal window, run the following commands in order: sudo apt-get update sudo apt full-upgrade sudo reboot Once your Raspberry Pi reboots, install Pulse Audio with the following command (it may already be installed): sudo apt-get install pulseaudio Then reboot your Raspberry Pi again with this command: sudo reboot Once booted, from the Raspberry Pi Desktop right-click the audio icon in the taskbar and select the correct (USB) audio device. Speaker Test You can also test the speaker from the terminal as well (follow the setup steps above first):

* Run 'cat /proc/asound/modules' to see what devices are being detected.

* The USB speaker is usually listed as device 1

* Run 'speaker-test -c2 -twav -l7 -D plughw:1,0' - that should play a female test voice.
