How to make Dialog work again?

[Dling]

My question is simple: how do I set up the Dialog? I need it for the htpc (yes, it would be possible to run a toslink connection from the pc to one of the Phantoms but I don't want to buy a new cable and it's also nice to keep the floor free from cables). 

Firmware 2.10.0

The Dialog is visible under 'My products'. But no sound.

I was curious enough to upgrade my Dialog, a 2 step process, first to 2.8.5 then to 2.10. Using 3 Ethernet cables to Golds, Dialog.

To enable optical from Dialog, go to the Devialet App, select room. Under Aux, there should be 3 optical inputs (for my stereo pair). Select Optical (Dialog).

Thanks for solving that puzzle. Much appreciated 

Now there's only one mystery left: when using the Dialog, the channels are "unbalanced". Left channel has ca 30 % of the normal full sound, the right channel works as it should. This happens (it has been there since the upgrade to dos 2) only when the Aux/Dialog-connection is used, not when the Phantoms are connected via wifi (which btw works much better after the latest firmware upgrade).
