@t3stin I don't know, I use a stock config and this is not set on my system. If you just want to test the sound, there's a command line speaker-test command you can use. Or download an .mp3 and play it from the command line with cvlc.
@77claws Have you tried configuring the sound output from the Audio menu in RetroPie ? Choose the Headphones jack as the default sound output and it should route all audio over the 3.5mm jack.

Thanks for the reply.
Removing the line autospawn=no enabled PulseAudio again if I'm not mistaking.
Already tried the 3rd answer on that thread with no luck.
@deceased10 turn the volume to 100%. Use the menu to quit and shutdown. During that shutdown process it will save your settings.
@mitu ok then, mupen64plus
