I tried to run raspberry on a CRT TV and there's audio on Kodi, but no audio on EmilationStation and games. I even tried to put audio from jack in menu, restarted and nothing happens.
A EmulationEstation bug? On kodi don't need any config, it's just on the go...
#audio_pwm_mode=2 --- disabled because very noise sound on kodi (only noise on games)
uncomment if you don't want the rainbow at startup
