      Hello,

      I run background music on my retropie raspberry pi 3 and when I start an emulation the music stop.

      I am using the py file music.py and the only emulator that does not stop the music is TI-99/4A I add in the music.py " ti99sim-sdl " but it does not stop when I start this emu.

      Hopefully somebody could help me why this is.

      Thanks,

        I'm trying to install this on EmulationStation on Windows, can someone help me or it's only for Linux?

            I am running a freshly installed and fully up to date image of RetroPie and when I set up this script the music will not stop when I start a game. I'm using RetroArch for everything and line 25 of my script looks as it should with retroarch listed as the first item in emulatornames. I started over from a clean install once already just to make sure I didn't mess anything up. My gut is telling me it's something in a recent update to RetroPie that's causing this. Can anyone help?

              @joelkolb I prefer the mpg123 method. The python script uses an internal array to check running instances of an emulator and then stops music. The method above makes use of runcommand-onstart.sh and runcommand-onstop.sh which is more hands on.
              If you want fade in and fade out effect on the mpg123 you can use this scripts here.

              If you are eager in python coding you can release annother version that will get rid of this "libary" and uses also the runcommand options. That would be a more straight way. It's not a direct answer on your question I know.

                @cyperghost I had used the mpg123 method previously but I never liked the way the music would stop abruptly when you launched a game so the fade in/out for with Livewire's method was nice. I'm happy to see that you came up with a method to do the fade in/out with mpg123. I will try this right away. Thank you!

                    @ExarKunIv Wow, nice and simple with RetroPie menu controls. This is great. I will give it a try. Thanks!

                      @ExarKunIv Oh yes forget about this. It uses mpg123 for mp3 and the fade feature was taken out from my script with much faster jumps in altering volume level so the fade is a bit messed (imho)

                              Hello,

                              it's working great here, thank you. I have some little modifications to enable fade in/fade out and also added the capability to not turn off the background music while playing but just lowering the volume. It works great with arcade ambience :)

                              The trick to make a smooth fade effect was to launch mpg123 with zero volume, in remote control mode and with the fifo feature.

                              There are four scripts involved and one ini file to be created in any path you want. In the scripts we will use the /path/to/ path.
                              The files are:
                              emulationstation_music.ini
                              is the file where we store the desired fade in while not playing games (volume_idle) and the final volume when the fade out occurs during playing the games (volume_game)

                              volume_idle=40
                              volume_game=10  # Put 0 to disable background music while playing
                              

                              mpg123_load.sh

                              #!/bin/bash
                              source <(grep = /path/to/emulationstation_music.ini)
                              echo "LOAD /path/to/music/arcade.mp3" > /tmp/mpg123fif
                              sleep 1
                              for ((i=0;i<=$volume_idle;i++))
                              do
                                echo "v $i" > /tmp/mpg123fif
                                sleep 0.1
                              done
                              
                              

                              mpg123_fadein.sh

                              #!/bin/bash
                              source <(grep = /path/to/emulationstation_music.ini)
                              if [ $volume_game -eq 0 ]
                              then
                                echo "LOAD /path/to/music/arcade.mp3" > /tmp/mpg123fif
                                sleep 1 
                              fi
                              for ((i=$volume_game;i<=$volume_idle;i++))
                              do
                                echo "v $i" > /tmp/mpg123fif
                                sleep 0.1
                              done
                              

                              mpg123_fadeout.sh

                              #!/bin/bash
                              source <(grep = /path/to/emulationstation_music.ini)
                              for ((i=$volume_idle;i>=$volume_game;i--))
                              do
                                echo "v $i" > /tmp/mpg123fif
                                sleep 0.1
                              done
                              if [ $volume_game -eq 0 ]
                              then
                                echo "stop" > /tmp/mpg123fif
                              fi
                              
                              

                              mpg123_quit.sh

                              #!/bin/bash
                              source <(grep = /path/to/emulationstation_music.ini)
                              for ((i=$volume_idle;i>=0;i--))
                              do
                                echo "v $i" > /tmp/mpg123fif
                                sleep 0.1
                              done
                              echo "stop" > /tmp/mpg123fif
                              echo "quit" > /tmp/mpg123fif
                              

                              Then I have modified the entry to start mpg123 in autostart.sh with:

                              /usr/bin/mpg123 -f 0 --remote --fifo /tmp/mpg123fif >/dev/null 2>&1 &
                              sleep 1
                              /path/to/mpg123_load.sh &
                              

                              the file runcommand-onstart.sh in:

                              /path/to/mpg123_fadeout.sh &
                              

                              the file runcommand-onend.sh in:

                              /home/gio/scripts/mpg123_fadein.sh &
                              

                              and the exit command:

                              /path/to/mpg123_quit.sh
                              

                              Now the bad news ;)

                              • At the moment I haven't figured out how to load music in loop mode with mpg123 when in remote control mode
                              • I'm using a single mp3 file (about two hours of duration), modifying the scripts to load a playlist shouldn't be an issue.

                              Of course there is room for improvements. I hope this is useful for you

                              Joe

                                Hi. A small suggestion about Synack method: as someone mentionned, if you have a splash video it delays the startup of emulationstation, because emulationstation waits for the commands in autostart to execute instead of loading.

                                A simple way to fix that is to launch the whole set of instructions in the backgroung (instead of mpg123 only). The only thing to do is to add parentheses:

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

                                No more delay ;)

                                  hello, I'm a noobie.
                                  But I have a question:
                                  Are you saying you have a code that will constantly play a mp3 file and play in the background and will continue to play while you do other things in the background
                                  using pygame?

                                  I got mine to play when i boot up the raspberry pi but, as soon as I do something like start my MAIN.py the mp3 stops playing: and I need it to KEEP PLAYING?
                                  Can you help?
                                  Thank you?
