Hi, I've also posted this on the HiFiBerry forum.
I bought a HiFiBerry Digi+ for my brother in law to play through the DAC of his AMR CD-777. The CD player has a single coaxial digital input. We tried it yesterday, but could not get sound. We had definitely selected the DAC as the source rather than the CD transport. Is there any reason why it wouldn’t work? Below is an extract from the CD player manual.
4.1 DAC Input (RCD-777 only)
The DAC button (RC4) is for the replay of music on the CD-777 from music stored on a computer hard-drive via an S/P-DIF or USB cable connection.
To establish the connection between the CD-777 and the hard disk source:
ii. Power ON the CD-777.
On the RCD-777, press the DAC button (RC4) to place the CD-777 in ‘DAC mode’.
Power ON the personal computer.
Connect the S/P-DIF input OR USB cable between the CD-777 and the personal computer.
Go to Control Panel > System > Hardware > Device Manager. In Device Manager wait until the personal computer in Hardware has recognized the CD-777 as a USB Audio Device.
This is found under the Sound, video and game controllers category.
Go to Control Panel > Sounds and Audio Devices > Audio. Make sure USB Audio Device
is selected as the default device under the Sound playback box.
Select playback music software on the personal computer (Apple iTunes®, Foobar®,
Winamp®, Windows Media Player®, Windows Media Center® et al).
