## Installation for Raspbian users
|
||
|
|
|
||
|
|
* Plug Audio+ firmly on top of your Raspberry Pi GPIO and turn on your Pi
|
||
|
|
|
||
|
|
* Open a terminal and type the following to download and run the installer:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
sudo wget -O - script.raspiaudio.com | bash
|
||
|
|
```
|
||
|
|
|
||
|
|
* Say yes TO the reboot
|
||
|
|
|
||
|
|
* On the next reboot you have to run the test to finish the installation (it is an ALSA oddness):
|
||
|
|
|
||
|
|
```bash
|
||
|
|
sudo speaker-test -l5 -c2 -t wav
|
||
|
|
```
|
||
|
|
|
||
|
|
* Reboot again and you will be able to control the volume from your desktop or by using the command-line tool `alsamixer`
