@Fantasens said in Sound not working with HifiBerry Rapberry Pi 4 with OSMC:

Is there no way to configure Retropie so that it behaves like Kodi by playing audio from both the TV and the Audio card?

'RetroPie' - or rather EmulationStation - uses ALSA. If you can configure ALSA so that it behaves like Kodi with the default card/output, then EmulationStation - and probably emulators - are going to work the way you want.

The only configuration for ALSA that RetroPie does is the one from the Audio menu, where you can choose between the audio outputs present on a Pi - Analog/HDMI. For more complex configuration you'll need to configure ALSA yourself.

I'll backup the chip tomorrow and save the configuration to my desktop PC.

Thanks for the help.
