External USB 7.1 Channel Sound Box
In most common cases, the digital CD playback function fails to run. This is
because USB audio is digital signal, it uses a different path to process CD music with
traditional analog CD.
You should open "Device Manager", select "DVD/CD ROM drives" and open it.
Then switch to "properties" page and enable digital CD audio.
4. When using software application program (e.g. Media player, Winamp,
PowerDVD, WinDVD....) to playback media files, can I plug out USB audio device
while playing?
It is the incorrect mode of operation because while application programs are
playing audio stream, Windows system is still using audio device to process
and deliver data real-time. So, when the user plug out USB audio device, the Windows
system cannot deliver audio data to the same device, hence the overlapping may
cause application programs / system to crash or fail.
The correct way to plug out USB Audio device is to stop playback function first
(Especially when your system is Windows
operation will enable a stable working system. Otherwise, uncorrected plug out may
cause application program or system crash.
Note：
Do not plug out while application programs are playing media files. Please
stop playback before plug out USB audio device.
