Quick and easy guide for adding music to Emulatonstation on RetroPie. Noob friendly!

Could this be used to give audio control to google assistant? I have it working in desktop mode but during emulation station bootups it cannot grab the audio control because the audio device is busy (presumably being used by emulation station itself) I wouldn't even need it to check for emulators running to reduce the volume because I would want the google assistant to be able to output during gameplay

Thank you for posting this guide, I just implemented the music player on my build and it works great!

I’m curious how this works in a set up with video snaps. Will the music pause or fade out when you are previewing a game video in the game select list? Or will it play over it and I should just wait until this is ironed out?

I believe I might've missed something or typo'd somewhere. RPI3 starts up and song starts in the 10 seconds. Go into game and when I exit said game, mpg123 does not continue at all. How do you go about editing this sort of thing? Thanks! ^.^'

Edit: I had checked and found that "[[ $(tty) == "/dev/tty1" ]] && pkill mpg123" was typo'd and missing a "K" in pkill. However that didn't resolve the issue.

@ssimmers In /opt/retropie/configs/all/runcommand-onstart.sh it should say:

pkill -STOP mpg123

In /opt/retropie/configs/all/runcommand-onend.shit should say:

pkill -CONT mpg123

SSimmers

@jonnykesh Awesome! That's exactly what it was. For whatever reason, I had "/pkill -CONT mpg123". No clue why I hit the forward slash the first time around. Thanks!

jonnykesh

@ssimmers Not a worry. Happy to help.

@cjax08 no, this still plays because it is an independent application running. What I have done to deal with this is I have re-encoded all the audio files that I use in my builds to be set at 50-60% gain. This allows for the audio of the video snap to come through clearly while you can still hear the bgm "behind" it for lack of better term.

anyone notice an issue where if you use the commands in bash script that music doesn't start up again when you go back into ES from terminal?

Is it possible to create custom launch file for specific rom that will not disable music?

cyperghost

@cool_iron YES and NO

I created two bash files that Continous or Disable Background music by using USER MENU from runcommand. If you launch a ROM then the grey box apperas... Press a button and you enter the runcommand menu list. Now you can enable/disable Background music by using User Menu item.
Take a look here and add a exit 2as last line!

The way I descripe is not 100% the method you asked here - it's a small workaround. Of course it is possible to add music for a specific ROM.... You can modify this code and add to runcommand-onstart.sh

i have done all commands on the rp3 direct
my big problem is where is the folder that i was created , when i type in mkdir /home/pi/bgm it say to me the folder already exists. But i cannot find the Folder on my PC or USB ...

COOL_IRON

@cyperghost I did not quite get it past the user menu step.
What should I do next? Can you explain this more please?
Maybe you could add some pictures?

cyperghost

@cool_iron
Add 2 bashfiles to dedicated folder descriped in the Wiki: runcommand functions
One with pkill mpg123 -STOP and the other with pkill mpg123 -CONT to User Menu. One file is called Stop BGM.SH the other is called Continue BGM.sh
Then you select one oft these files in User Menu and can manually enable or disable music. If you follow the link that I gave you to the bash script then you can automate the process by using a custom collection as trigger event.
But this needs some coding skill...

Feel free to ask ;)

COOL_IRON

@cyperghost Oh, sorry, I didn't read the topic of this discussion :P
The problem is that I am using different method for background music. Is it possible to make this two .sh scripts woking with this method?

@retroprogrammer please don't spam. The official docs are there for a reason

cyperghost

@cool_iron I think there is no problem to install mpg123 as background player just for in game music. This would be the easiest solution.... And if there are occouring problems you can easily remove it.
As you use the python method the python code checks for process PID of a running emulator in background so it seems to be impossible without altering python code. But that's out of my class.

EDIT:
Maybe you can act like this!
I think about a code like this ...

Enable ingame BGM.sh

#!/bin/bash
# PSEUDOCODE!
# DISABLE python check for running processes of emulators by pausing the python script!!!!
# OMXPlayer will still run in background and will play music!
pkill -STOP "python backgroundplayer"

and by editing runcommand-onend.sh you always set the -CONT condition.

But why don't you give the mpg123 no chance? Imho it is the easiest method for BGM but keep in mind that mpg123 is just a small player with a small bunch of command line arguments...

@retroprogrammer Before spamming this thread you can ask @meleu if he want's to add your tuts into his Useful topics thread

retroprogrammer

sorry for spamming guys just wanted to say that their are some other tutorials other sorry :(

Having some issues after getting music playing in the background via this tutorial. On launch of any ROM I am getting an audiomanger error stating the device or resource is in use. Once the game loads I have no game audio.
