can I add support for pi2scart in retropie?

Can I add support for pi2scart for retropie on raspberry 3b+ in simple way (without reinstall or change system)?

@martinex depends on the status of your current image.
If you just installed the retropie image for the Pi3B + and everything is on default: no problem, just follow the guide on the Pi2Scart Homepage.
If your image is allready tweaked and configured in any manner: might end in a mess.

All work, but there is no sound in games (in Menu emulation station I got music/sound).

Go to the Audio menu in RetroPie and re-configure your sound device - choose Headphones since I assume PI2Scart will use the audio jack on the Pi.

If that doesn't work, then add more info about your setup, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first.

I was changed to analogue, headphones etc. Always music works only in Emulation Station, but no sound in games (tested on PSX and SNES), when I back from game to Emulation Station sound works again. No working only in games.

Raspberry 3B+ +pi2scart, connected via RGB cable and jack 3.5" to speakers.
Retropie 4.7.1 I always do upgrade via sudo apt-get update/upgrade and update from scropt menu to have all latest.
Dual Shock 2 connected via adapter to USB.
Retropie was downloaded and flashed from main page of retropie project.

Get a verbose log from the emulator and post it on pastebin.com to take a look.
If you have a $HOME/.asoundrc file, then post its contents here in the topic.

The audio configuration (~/.asoundrc) is ok. I suspect the configuration file for RetroArch is causing this:

audio_volume = "0.000000"

I suggest you rename the file, then reinstall the PS1 emulator (lr-pcsx_rearmed) before starting any PS1 game.

@mitu there is no config for all emus?
SNES, NES, Amiga and so on. SNES doesn't have sound, too.

Yes, but you've overwritten the default config when you used 'Save Config' from the RetroArch's menu. In the default config, there is no volume or sound device set, whereas in your config there is.

@mitu
I changed device to pcm and volume to 50.00000 no effect.
