Background Music [Continued from Help/Support]

N0va

@synack Hey man I am having some trouble here. I got the music playing at the home screen but when I enter a game the music does not stop. When I first did this I noticed there was no runcommand-onstart.sh and runcommand-onend.sh I had to create them. I think this is the problem any suggestions?? Any help would be appreciated.

(Also side note not as important, any way to decrease volume of music without decrease monitor volume?)

@retrobean Not to derail the thread or take away from @Livewire's contribution here, but you can also just use an external mp3 player such as mpg123 to play music without worrying about details.

install mpg123
sudo apt-get install mpg123
edit /opt/retropie/configs/all/autostart.sh and before emulationstation is called;
while pgrep omxplayer >/dev/null; do sleep 1; done
mpg123 -Z /home/pi/bgm/*.mp3 >/dev/null 2>&1 &
edit /opt/retropie/configs/all/runcommand-onstart.sh
pkill -STOP mpg123
edit /opt/retropie/configs/all/runcommand-onend.sh
pkill -CONT mpg123
edit /home/pi/.bashrc and add
[[ $(tty) == "/dev/tty1" ]] && pkill mpg123
This will randomly play mp3s from the specified folder (step 2), pause the player upon entering a game, resume when exiting, and also stop the player when exiting emulationstation and dropping to a bash shell.

I'm following this method but I have an issue on autostart.sh incorrect syntax on line 4. This is how I have set up autostart.sh:

while pgrep omxplayer >/dev/null; do sleep 1; done
mpg123 -Z /home/pi/bgm/*.mp3 >/dev/null 2>&1 &
emulationstation auto#

I don't get it where I wrong, the synack's code is before the emulationstation and there isn't a line 4!

It looks like in your 1st picture of /etc/rc.local you are trying to execute /home/pi/PyScripts/Test1.py but
in the 2nd picture (unless I'm mistaken) is of ???/pi/.config/PyScripts/Test1.py

The 3rd picture I can't tell if it is correct unless I see what's inside your Test1.py

ive changed the folder Scripts to PI/Scripts but it doesnt work:(?

i havent changed anything in the script so the music folder shall be in roms right?

The other thing I would check is if that Script is executable. Run this to make it executable:
chmod +x /home/pi/PyScripts/Test1.py

If it already was executable running this will not harm anything.

Yes @Livewire's script uses /home/pi/RetroPie/roms/music/ for the Music directory

retronerd

Thanks but that doesnt solve my problem????

@retronerd
Oh, make sure in /etc/rc.local that (sudo python /home/pi/PyScripts/Test1.py) & is all on one single line.

Your 1st picture shows it on 2 lines.

retronerd

ive changed to 1 line but doesnt work

@retronerd

ive changed to 1 line but doesnt work

Hmmm....just to verify, did you run sudo apt-get install python-pygame

retronerd

@backstander yes what im doing wrong?

retronerd

@retronerd

what im doing wrong?

Hmmm...I'm kind of stumped right now.

look at the S on script is that right? its from 1 page here

That uppercase 'S' is correct in /home/pi/PyScripts/Test1.py

Your picture of the Test1.py looks correct as well.

retronerd

@backstander thats strange! ?????

@backstander
can i unistall this and install it again somehow?

backstander

@retronerd
To uninstall use the step I posted above here:
https://retropie.org.uk/forum/topic/347/background-music-continued-from-help-support/125

Also here is an alternative script that kind of does the same thing. Maybe try to follow this one instead:
https://retropie.org.uk/forum/topic/347/background-music-continued-from-help-support/43

retronerd

@backstander ive tried the alternative script but i got this error?

backstander

@retronerd
Try this first:
sudo apt-get update

Then try:
sudo apt-get install mpg123

retronerd

its seems to download:)
how do i edit /opt/retropie/configs/all/autostart.sh which command?

backstander

@retronerd

how do i edit /opt/retropie/configs/all/autostart.sh which command?

Most of us use that program "nano" to edit files from the command line. Examples below!

step 2:
nano /opt/retropie/configs/all/autostart.sh

step 3:
nano /opt/retropie/configs/all/runcommand-onstart.sh

step 4:
nano /opt/retropie/configs/all/runcommand-onend.sh

step 5:
nano /home/pi/.bashrc

If any of those won't let you save your changes, then add sudo before the nano like sudo nano blah blah blah...
