Very low volume from Optical Line Out

I have a ZP90 connected via "Coax/Digital Line Out" to my DAC/Amplifier in my living room.

I would like to be able to adjust the volume from my Sonos Controllers/APs. Thus, I have the Output level for the "line-out" set to "Variable".

However, with this setting the volume of the output is very, very low. I have to turn the amp up to almost full volume to reach a "normal" level.

If I switch to "Fixed" level on the Line out volume, the level is fine - but then I can only adjust volume on the amplifier, not on the Sonos controllers.

Dose anybody have a solution?

    same here. its very annoying. im using a cheap soundbar. its a insignia one...and it has this same issue. i returned it b/c i was like hmmm...must be the soundbar. but nope. they gave me a new one and same thing.

    i can hear the music coming out the soundbar....and its very very low...and then all of a sudden the volum will go up to the normal volume. then it will go back down.
