Devialet starts playing at volume level -12

[Soniclife]

In the configurator there is a setting for the start up volume, and that is -40.0 as a default. I assume you have adjusted that setting? General settings, in the upper left corner of the configurator screen. I can't help with any aspect of JRiver, but I would think that the configurator setting would overrule any other music interface.

I think you may be able to set input sensitivity for a particular input, but I think you are talking about the output volume, correct?

I use a Sonos Connect, and the input to the Dev is set to 'fixed' which means full volume from the Connect to the optical input. The Dev volume always controls the volume, and i've never had it start at any volume other than -40.0. That start up volume is of course only implemented when the amp is woken up from stand by.

Well, that's the thing, the Devialet is set tot the defeault -40, that's why it's strange. It only occurs when using Air over ethernet (i don't use wifi). Despite what i change on the Devialet or the PC, it starts playing at -12... Strange so to say, and annoying...

Have you tried with a default configuration?
