Jriver and Devialet

[patcam]

I want to use Jriver with my mac-mini connected to the Devialet by Ethernet. I have some trouble with the bit perfect, the 24 bit/96 KHz is not recognized by the Devialet (It always configured with 44.1Hz).
In the devialet, when I press a long time the source button, it is indicated 44.1 KHz !
There is no such problem with the windows version of Jriver, but the sound is not so good than with the mac.

In Jriver , I use core audio (direct connection), it is writen "no changes are made" but the output is indicated 96 KHz,32 bit instead 96 KHz,24 bit . It is probably due to the "integer mode" not supported by Air.

For Windows, Air proposes the general Wasapi for bit perfect, but for OSX, it is proposed only for Itunes and not for OSX core audio. Maybe it is the origin of the problem

Note: With Mac, Jriver and Itunes are similar for sound quality, but Jremote is more developped than Remote for Itunes, especially for a big album collection (> 600)

If you can help me

Thanks
