Tidal IOS volume control not working via optical to Phantom

[alandbush]

Hi I use Yamaha to select input but not to control volume it’s just set to max volume and volume can’t be adjusted  (player option selected instead of Preamp option)

I presume you have tried Preamp mode with no success?

Only curious because I’ve assumed that the Airplay audio signal contained a volume command.
If so, then the command would be applied by the Yamaha except when in Player mode.
