Works. Had to turn off and on a few times too, not just initially but after I had put the iPad to sleep for a few minutes.
It is particularly great because I have the Audeze EL-8 headphones, with the Audeze Lightning cable that contains a DAC and amp, powered by the iPad. Like it better than the iPad’s built-in DAC and amp. I have used the EL-8s plugged into a SonicOrbiter SE plus a LHLabs Geek Out on my bedside table, works fine but it is stuck in place, now I am mobile! Well, mobile within my wifi range, but still. Lovely!
(With this setup, hardware volume control is in the Audeze DAC/amp/cable, but it all works, I can adjust volume with buttons on the cable, with the iPad’s hardware buttons, with the Roon app, or with iPeng, and wherever I adjust it, it is reflected accurately in all the places. And the cable has a mute button, and it pauses Roon! Isn’t it lovely when things work like they should?)
Well done!!!
