Expert Pro 440: Problem connecting Companion
#15
Update:

I finally reached Devialet, through Whats App (!), although this I guess is only partly true since the answer was "Generated by AI". The answer I got referred to the basics; i.e. format SD card->create new config. I disconnected the power cords and formatted, created config and downloaded. I then inserted the SD cards before replugging the power cords. The config loaded on both units, the Master window saying "November 2025" (the name I´d given the configuration) and the Companion window saying "S1 CONFIG".

I really don´t know why the Companion suddenly works... Is it beacuse

1. It´s been powerless for a week or so
2. I unplugged the power cords before inserting the SD cards (although I´ve tried this before)
3. I "manually" added .txt to the configuration files names (but this is usually done automatically when it´s a text file and you press save?)
4. I excluded some step in the Configurator (I´ve previously turned off some inputs that I don´t use, e.g. "Optical")

The cable between the units is the same that I´ve used before.

All I can say is that it immediately struck me how much better it sounds than when I could only use one of them (220 vs 440)

Feel free to comment!

Best regards,
Mikael
