No Sound in N64 mupen64

[FlightRisk]

I have a RPie3B, overclocked. I had n64 roms working when I was using a HDMI to VGA converter, but switched monitors. Now sound does not work for any N64 games. I am testing mostly with "007 0The world is not enough", because I am using the 3.5mm audio jack for now (there are no speakers on the monitor). I was using mupen64 Auto at first. Then I tried the lr-mupen64. With that emulator, I get audio, but the game is completely unplayable, about 5 fps, broken graphics, etc. I tried the other mupen64 cores and none of them send sound out of the 3.5mm jack. I tried everything to edit the mupen64plus.cfg file and change OUTPUT_PORT from 1 to 0. But first, the numbers are in quotes when nothing else is:

OUTPUT_PORT = "1"

I have tried with and without quotes. And second, my changes save. But as soon as I run any N64 roms, it changes the file! When I go back and look at it, something keeps changing it back to 1.

BTW, I noticed the "lr" core smooths the image. But the defaults for the regular mupen64Plus are amazing. Other than the sound, the resolution and the FPS are good so far.

@flightrisk Try this:

/opt/retropie/configs/all/autoconf.cfg

change

mupen64plus_audio = "1"

to

mupen64plus_audio = "0"

I knew there had to be something overriding my settings. Thank you for this. Finally working again. I went back to the docs and read more about settings. Glad it was simple. Now I can figure out all the settings in these emulators and see what works best.

I have a moniter with no speakers so I am using USB speakers. When I use
Lr-mupen64plus I get audio but of course that version is really pixelated. So when I use any of the other emulators I get no sound. Such as when I use mupen64plus-gles2rice-highres I get no sound. Could you help me?

@h3rmitpl4ys Doesn't your monitor have an audio out jack? Sometimes it is hard to see. You send the audio out the HDMI, and then the monitor picks off the audio and sends it out the jack. If not, then I'm not sure as I have only used the audio jack on the Pi or HDMI.

@flightrisk The monitor is an old vga monitor no audio or HDMI jacks. I use a vga to HDMI converter. I am using USB speakers that I already set up. But my only problem is the emulator. I only get sound using
lr-mupen64plus.

Thank you Quicksilver for the fix. I know this was six months ago, but just found this thread. I'm new to retropie and the lack of sound in n64 emulators was making me crazy. Cheers buddy :)
