Phantom Gold, startup sound but no music

@Mohmm I don't think you have bricked your speaker.
Here's the link to the reset procedure. It's different to the one you performed.

You'll have to add the speaker to your system in the Devialet app after the reset.

Thanks, st33f and ragwo. That did the trick.

Wonderful to have a stereo pair again.
