Am i doing something wrong?

[samurai7595]

I'm experiencing inconsistency on preout in my D200, too. I've confirmed twice and even thrice just to make sure the "mute applies.." is clicked off. In General option, I have set preout to off as default and on Remote config, I have set the bottom right button for Pre-out on/off function. So, when I need to listen to headphone, I can turn on the pre-out and press Mute to switch off the speakers. [In case, you miss the Tone/Balance function (defaulted on the bottom right button) just press and hold for 2 sec on the Mute button and you can access this function. ]

I'm using the PREOUT for my Dynaudio XEO transmitter for my wireless Dynaudio XEO 3 speakers (kitchen).

The only thing I needed to configure was the PREOUT settings (see photo) and I did not change anything else on the Devialet.  Also, under General Settings, I left the default of Sub/Preout enabled (see photo).  When I want to listen to music in my kitchen only, I mute my main speakers (living room) and using the Devialet remote or Devialet Remote app, I can adjust the volume on the speakers in the kitchen.

This setup has been working flawlessly for a week now.
