It’s doesnt work in Roon on Android, nothing does. As I explained earlier. Nothings changed here. Roon tested means it will work connected to a computer or streamer that has usb audio out of iOS devices.
Saying that you can use it to ouput audio from Roon but it won’t be bit perfect as Roon wont see it.
Yes and no. iOS works with external DACs properly and Roon will see it as part of the chain in most cases. Android doesn’t due to the current limitations of the OS. You can code around it as UAPP have, but currently Roon does not so you get system audio and not bit perfect exclusive control. This results in most apps Roon included currently outputting at 48/24 only,.Qobuz, Tidal are all the same. Roon are working on a refresh for Android that hopes to work like UAPP and work around the limitations of the os.
