Description of Issue

I have a wakeup problem with my Lumin U1 mini.
I have one zone with two devices:

*Lumin U1 mini Bridge device USB output
*Kii Audio control audio device USB input
The problem is: when I start a stream and klick on ‘play now’ then there is a blue pop-up screen with the text “select audio zone”, which text disappears immediately after that.
The stream does not start.
When I klick the second time on ‘play now’: the stream is indeed playing!
Automatic sleepdevice is set in ‘Roon device setup’.
The only option is that I do not put the Lumin U1 mini in the standby mode in order to start the stream in one click.
I have two other devices of Naim: Muso 2 and Muso QB 2, which start both immediately in one click on ‘play now’.
The question is: is this problem of not fast enough finding the zone a Roon- or a Lumin-problem?

Hi Roonsupport,

I did not receive any response on my question (see above)
I have tested many steps in order to find a solution for my wakeup problem with assistence
of Peter Lie from Lumin
The Lumin U 1 mini is a Roon Ready device.
And the Kii Control is a Roon tested device.
It is a pity that this is no guarantee for a good working system in combination with USB.

I have been thinking of some possible solutions:

  • let the Lumin U1 mini in power On situation with the display Off for 24/7 (higher power usage)
  • make the Lumin U 1 mini connect with AES XLR connected to Kii Control (disadvantage a longer
    special cable)
  • other endpoints: Naim ND5 XS2 or HiFi Rose 250

I am still wondering which solution is the best in my situation.
Maybe you have any suggestions?
