@Zing sorry about that example, that line does not reflect how my recalbox.conf looks like, which is :
## Videosnaps
### Delay before videosnaps start, in millisecond. Default: 2s
emulationstation.videosnaps.delay=1000
### Video loop times. 0 = no video. 1 or more = the video loops x times before fading out
emulationstation.videosnaps.loop=100
### Enable videosnap sound/music
emulationstation.videosnaps.sound=1
Again no matter if you set it to 0 or 1, no difference - no sound in either way.
