AutoStart

Category: Raspberry Pidq @ 8:27 PM

Essentially all you have to do to create a start-up script is the following:

Create a file here and make it executable:

sudo nano /etc/init.d/start-sound && chmod +x $_

Add it to the default runlevel:

sudo update-rc.d start-sound defaults

All your script really needs to do is call aplay on an audio file. Something like this:

# /etc/init.d/start-sound




echo "Playing startup sound"
aplay /path/to/file.mp3 2>&1 >/dev/null &

AutoStart the Jack Server

nano ~/.config/autostart/jackd.desktop

[Desktop Entry]
Type=Application
Name=Jack-D
Exec=jackd -p 8 -r -m -d dummy > /dev/null 2>&1
StartupNotify=false
###
Comment=Setup JACKD to prevent messages
NoDisplay=true
###Exec=sh -c 'xset m 20/10 10 r rate 500 30 b on'
###NotShowIn=GNOME;KDE;XFCE;




 

Instead of aplay use omxplayer which can read MP3, AAC, WAVE and a few others.

# /etc/init.d/start-sound
echo "Playing startup sound"
omxplayer /path/to/file.mp3 2>&1 >/dev/null &

omxplayer is pre installed with the latest (for a while now) and also you can do the same to play video to a selected output device.

If you get permission error try putting sudo in front of omxplaye


Make The Startup Sound Part Of The Boot Process

Use the nano text editor to open up a file called rc.local within the /etc directory:

sudo nano /etc/rc.local

Scroll down to the bottom of that file, and just before the line that states exit 0, add the following line:

omxplayer /etc/sound/logon.wav 2>&1 >/dev/null &

Again, remember to replace the file name logon.wav with whatever you have called your audio file. Once you have added the line to the rc.local file, use Ctrl+O to write out (save) the file and then Ctrl+X to exit.
