Have you gone into Roon's Settings > Audio to see if the Metrum is shown there and enabled?

Need help with Roon, system output is not showing by Streamer/DAC
I can’t play digital music thru my 2-channel system. My Roon server is my iMac desktop computer. When I click on the "system output" (on the bottom right of the Roon window), it no longer shows my Metrum Ambre Streamer. A couple of days ago, I restarted my computer, and it did bring up by Metrum streamer. Now it doesn’t work. I not a computer whiz, so I am at a loss. Meanwhile, I have no music thru my 2-channel system.
My system is Metrum Ambre streamer (on LAN with ethernet cable), Metrum Onyx DAC, Atma-Sphere MP-3 preamp, Atma-Sphere Class D amps, Acoustic Zen Crescendo Mk II speakers.
Please help. Thanks!!
