Install the MPD Music Server & Configure audio service in Raspberry Pi

Installation

MPD ( Music Player Daemon ) is a lightweight server for sharing a music library both locally and over a network. The MPD allows not only the music to be shared and played over the network, but also allows for numerous different front end clients.

Installing MPD is very easy and lightweight. Just update your system and install using the package manager. For Ubuntu :

sudo apt-get update  
sudo apt-get install mpd --no-install-recommends 

Disable automatic recommendations Disable recommendations temporally (for single package installation), adding the --no-install-recommends option: sudo apt-get install package --no-install-recommends Disable recommendations permanently, using apt.conf file: echo -e 'APT::Install-Recommends "0";\nAPT::Install-Suggests "0";' | sudo tee /etc/apt/apt.conf

That's all. Now you can check the status of mpd by using

Start MPD service automatically on boot sudo systemctl enable mpd

Configuration

MPD uses a text configuration file. If you are working from the command line , open the following file with Vim, Nano or any favourite editor. For GUI, you can use multiple editors.

sudo vim /etc/mpd.conf

As a reference, you can use this file :

Sound Problem

The Raspberry Pi has two audio output modes: HDMI and headphone jack. You can switch between these modes at any time.

Idea 1

The following command, entered in the command line, will switch the audio output to headphone:
amixer cset numid=3 2

Here the output is being set to 2, which is HDMI. Setting the output to 1switches to analogue (headphone jack). The default setting is 0 which is automatic.

Idea 2

Open up raspi-config by entering the following into the command line:

sudo raspi-config

Select Option 7 Advanced Options and press Enter, then select Option A6: Audio and press Enter.

If you're still not getting sound via HDMI

In some rare cases, it is necessary to edit config.txt to force HDMI mode (as opposed to DVI mode, which does not send sound). You can do this by editing /boot/config.txt and setting hdmi_drive=2, then rebooting for the change to take effect. -Source: https://www.raspberrypi.org
