This is an update for the older post with Debian Wheezy on how to setup a Raspberry Pi with Raspbian Debian Jessie in order listen webradio.
Download Raspian Lite, extract the zip file and copy the image onto your microSD card using the linux command line:
sudo dd bs=4M if=2016-09-23-raspbian-jessie-lite.img of=/dev/mmcblk0
The Lite version is already very slim, so there is no need to remove unneeded packages later, i.e. a X11 server is not necessary for headless running.
Instructions for other operating systems are described at: Writing an image to the SD card.
Insert the SD card into your Raspberry Pi, connect the Power and Ethernet cable. Raspian will get a IP through DHCP, so login into your Pi by SSH using the default user pi and password raspberry to make the base configuration and a system update:
Now expand the filesystem, set a new password, run internationalization options, change the hostname in the advanced settings and reboot.
After that install the latest updates:
sudo apt update
sudo apt upgrade
Connect the Raspberry Pi using a 3.5 mm cable to your radio through the AUX input and install Mplayer:
sudo apt install mplayer2
To test your setup with you favorite webradio stream url. In my case sunshine live:
Useful mplayer commands:
9/0 -> lower/higher volume
q -> quit
Maximize alsa sound output:
amixer cset numid=1 -- 400
Run webradio at startup with Debian Jessie
The old /etc/inittab from wheezy does not work any more, because SysV is replaced by systemd as init system in jessie.
Create a new file i.e. /etc/systemd/system/mplayer2.service
Desription=mplayer with systemd respawn
ExecStart=/usr/bin/mplayer -nolirc -ao alsa -vo null -really-quiet http://stream.sunshine-live.de/hq/mp3-128/Facebook-og-audio-tag/
and activate it
sudo systemctl enable mplayer2.service
reboot or start it manually
sudo systemctl daemon-reload
sudo systemctl start mplayer2.service
