How to mute game sound only.

Yonut

I'm looking to play music when I'm in RetroPie. Everything is working correctly, both joysticks, music player, and RetroPie.

The problem is that I can't figure out how to block the games sound f/x from the audio out. It seems that muting feature of Retropie mutes the whole system, not just the game.

Is there a way to stop the games sounds effects and not have the whole system muted?

@Yonut How are you muting ? Which Emulator ?

Please do not post a support request without first reading and following the advice in https://retropie.org.uk/forum/topic/3/read-this-first

@BuZz Sorry, I didn;t think things like 'Power Supply Used' were relevant to this.

RPI 3
Power Supply 2A
RetproPie 4.1
SD Image from website
2x USB Xbox controllers connected and working
No error messages received
Log not relevant (or is it?!?)
No guides used
Emulators: lr-fceumm (for nes); lr-stella (for atari)

Just need to know how to mute the game and not the system. The only option I have available is when I hit start, a white menu comes up and under 'Sound Settings' there is a mute. I don't know of any other way under Retropie to stop the games sound.

It looks like Stella has a '-mute' option, but I don't see where I can add this to?

Power supply may not be, but lots of the other information is - but as you are asking for help, it's best just to provide as much information as you can and let us decide what is relevant.

You can mute libretro emulators via RGUI -> Start+X / Settings / Audio

I can't find RGUI or startx on RetroPie. How do I access this?

BuZz

@Yonut you press start + button X in game. See the retropie retroarch documentation

Ty, but turns out it is select + X. It's also RGUI -> Settings / Audio

I found out it works on half of my ROMS, but the other half won't load at all when the 'Audio Enabled' is set to 'OFF'. I don't know where the problem is, and I'm tired.

@Yonut well i got the settings / audio location right, but yes, select + x. Guess I'm tired.

Perhaps the option affects some games. Don't know as never used it.

Yonut

Ok, you can't use 'Audio Enabled' or 'Audio Mute' because not all roms work.

But you can make 'Audio Volume Level (db)' to '-80.0'. Seems to work on all roms.

@BuZz Ty for your help.

Yonut

Ok, solution found. I don't know why the two settings are different... but anyway.

I was able to stop all game sounds for nes by editing the file:
/opt/retropie/configs/nes/retroarch.cfg

audio_enabled = "false"

This works and doesn't stop the roms from working like using the select-X method. Now working on atari (stella)
