Mupen64Plus - No sound in Rareware games (non-libretro)

  • @mitu No, I've been using a logitech F310 gamepad

    @Ashrill Can you post an emulator log ? Start the game - notice that you don't have any sound - then exit the game and upload the /dev/shm/runcommand.log to, maybe we can spot the error.

    @Ashrill It seems you're running with the sdl-audio plugin - can you try switching to the omx plugin and see if that makes a difference ? Modify /opt/retropie/configs/n64/mupen64plus.cfg and change the AudioPlugin configuration to

    AudioPlugin = ""

    then boot up again a game that doesn't work.

  • @mitu Thankyou! That seems to have solved the problem. Would there be any reason to switch back to SDL for some games or is OMX just generally better?

  • Why did SDL audio not work?

    @Ashrill Franky I don't use N64 emulation that much, so I'm not familiar with the inner workings of the audio output in Mupen64Plus. The SDL audio should work - as it works for most people -, the only difference in your config is the manual installation. You could play with alsamixer and aplay to check your sound card options/settings, but since you're only using HDMI and not an USB/external sound card, it shouldn't make a difference.

    Check the default volume on the sound card with alsamixer, maybe it's actually close to zero and, while the lr can use alsa directly to control it, maybe the SDL audio plugin in Mupen64plus doesn't.

    EDIT: is there any reason you used the NOOBS option to install RetroPie instead of using the RetroPie image ? You can find one that supports the 3A+ at .

  • @mitu I originally used this pi as a portable general purpose machine and didn't want to have the hassle of having either a separate SD card for Retropie or having to fiddle around getting my data and settings back to normal after re-imaging.
    alsamixer was set to 100, so that doesn't seem to be the issue - OMX seems to be working fine so it's no problem if you're not sure about the cause of the SDL-audio problem.

  • @mitu
    Thanks for the new commands, this one is kind of cool.
    alsamixer shows only one card:
    bcm2835 ALSA
    while lowering the default volume does make it quiet, the libretro emulators are also quiet.

    Noobs is an easy way to have a dual-boot and manage startup. But using retropie there isn't much of a reason to dualboot. Retropie should have a startup option to disable or select how you want to use your device.

  • @Ashrill just be aware save states will not function when using omx as the audio plugin. Also the default volume is insanely loud and can't be adjusted as far as I know.
