No Audio from Headphone jack (analog)

  • Dell/Wyse 3290 Thin Client

    LibreElec 9.0.2

    Builtin sound chipset (Realtek ALC231)


    Everything else seems to work well, and I can get sound from the builtin speaker - but no sound is output from the headphone jack on the front of the unit.

    I've attempted to play directly to all of the devices listed in 'aplay -L' - but I can only hear sound from the builtin speaker.


    Not really sure what else to do. Google reports some linux patches way back in 2013 - Is there a possibility that this isn't included in the current 9.0.2 kernel?
