im an total newbie in rpi. ive got the newest retropie sd image (ver 1.9) and have set up and update the binaries. then i have installed retroarch. here is the problem. when i start emulationstation i see all my games in the neo geo map. when i start metalslugX is see a loading screen from final burn alpha february 8th 2014 then starts metalslugX and its playable only there is no sound at all. same thing in Nes,SNes and dgen emulator. all games are can be played but no sound at all. Does anyone have a solution to solve this problem?
my sound is connected through HDMI.
i git sounds from emulations station when i select a game i hear a sound. the game starts and is fully playable only without sound. in retroarch cfg seems everything ok..
