The Raspbian OS contains the standard distribution to play .wav files. However, if you want to play MP3 files, install the mpg321
library by executing the following command in the terminal:
sudo apt-get update sudo apt-get upgrade sudo apt-get install mpg321
You can play MP3 files with the following command:
mpg321 "my file.mp3"
Remove boot messages
Go to the Raspberry Pi terminal and enter the following command:
cd /boot/ sudo nano cmdline.txt
At the end of the file, add this:
loglevel=0
The preceding line would suppress every log from the kernel. Reboot the Raspberry Pi, still you will see some messages. To remove these messages, use the following code:
cd /boot/ sudo nano cmdline.txt
Change console...
