Fidelio A9

I can’t use Fidelio A9 (aw9000)
I have seen on the homepage of this site that Fidelio A1 is supported.
A9 is the same product on firmware upnp

I see my Fidelio A9 in the list but no sound are playing
I tried with different parameters but no luck …

Is anybody at Fidelio A9 in this forum ?

Many Thanks
