N64 mupenPlus sound volume

[Hyell]

Hello,

I got a Pi3 with retropie 3.6 (install from sd card)

I'm trying to adjust audio volume when a game started with gles2, glide or rice pluggin. (I use headphone and officiel raspberry display, so I cannot change the output volume on my display)

I try to change /opt/retropie/config/n64/mupen64plus.cfg and add :
VOLUME_CONTROL_TYPE = 1
VOLUME_ADJUST = 5
VOLUME_DEFAULT = 20

By I don't have any volume change when I start a rom.

Somebody know if it's possible?

The default audio plugin is mupen64plus-audio-omx.so, which does not have volume control. You can change this plugin to the sdl version for the control, but sdl's default volume setting is about where you would want it anyways. Omx is 3-4 times louder than all other emulators for some reason, but sdl is pretty even with the rest. There will be a settings block generated in mupen64plus.cfg after your first run with this line changed to AudioPlugin = "mupen64plus-audio-sdl.so".

Be aware there was an old bug with using the glide video plugin with the sdl audio plugin. The screen would be black, but audio would be playing. It has been fixed for a while, but you're on an older version, so you'll probably need to update the retropie-setup script and install the mupen64plus emulator to avoid it.

Ha ok, I don't read that ^^
I just change the audioplugin and it's working fine. (and no problem with glide ^^)

Thanks you very much :)
