I also can choose in the sound-menu of the iMac the Apple tv as a receiver and it works.
But this doesn't:
So why can't I get a connection with the Oppo (front USB and back USB-DAC)?
Of course I try to select: 'Please set "System Preferences -> Sound -> Output" to "OPPO USB Audio Device 2.0".
but the Oppo isn't even mentioned. (Plugging - unplugging - plugging wan't help.)
It doesn't matter if I have chosen the USB-port for the input (Input - 8).
Just let me add that I use the latest Beta Fw.
Are you sure you aren't confusing the two types of USB socket on the player?
The thin rectangular USB sockets on the back (and also one on the front) are for attaching peripheral devices like a hard drive, a USB keyboard or the Wifi dongle.
To attach your Mac directly to the player, so as to use the OPPO as an audio output device for the Mac, you do *NOT* want to use one of those thin-rectangular sockets.
Instead you use the Asynchronous USB DAC Input -- a square-shaped socket -- on the back of the player.
You'll need a USB cable which has that square-style USB plug on one end and the thin rectangular-style USB plug for the Mac end. These are readily available where USB cables are sold.
When plugged in that way, the OPPO should automatically show up as a Sound Output device in System Preferences > Sound > Output on the Mac.
Select the OPPO as your Sound Output device on the Mac -- i.e., so the Mac sends audio there instead of using its built in speakers.
On the OPPO, press Input and select the USB DAC Input.
Any sound the Mac produces -- such as by playing a music file -- will now play through the OPPO.
