Sound problem

After updating my Vero 4K + I have no dialogue when the audio format is aac 5.1. Applies both via TV or amplifier. If I change the number of channels to 2.0 in KODI, the dialog will be heard. I have no sub so I have set the channels to 5.0.

If you set to 5.0, loss of FC channel when playing to a TV is expected.

If you do have a FC (front center) speaker, check that it’s working (!), if you don’t then check you have told your AVR that so that the AVR mixes FC to FL and FR because Kodi won’t do that.
