Description Of Issue

System worked perfectly for several months. Now Devialet issued a software update which I uploaded to my device, with the result that the device is now flagged „uncertified“. Streaming is only possible via „AIR“ with limited sound quality. Will this effect now always occure after software updates by Devialet? When can I assume the issue to be solved?

Power cycle your Devialet, roon core, and router.

Thx a lot, dinosaur! System works after rebooting all three devices without having them in one power circuit. Getting them all in one circuit will only be possible with some groundwork within our flat.


Hello @Michael_Hinz,

Thanks for letting us know that the reboot sorted this issue out! If this behavior re-occurs, please just let us know and we can look into this further, thanks!
