Check Konfig > Device > "Dual Analogue/Exakt Stereo Output" has been enabled.
If you have declared your Exakt speakers as 'Front Left'/'Front Right' and the analogue outputs to be 'Front Left'/'Front Right' (Stereo). ensure that this option in Konfig is enabled. The audio in the Exakt outputs will be out of sync by approx 45mS compared to the analogue outputs.
