FAQ & Technical:

Q1：When using software application program ( like: Media player, Winamp, PowerDVD, WinDVD…) to playback any media files, can I plug out USB audio device while playing?

It is incorrect mode of operations, because while application programs were playing audio stream, Windows system is stilling using audio device to process and deliver data real-time. When users plug out USB audio device Windows  system can not deliver audio data to the same device, so that system will be confused and make application  programs failure or system crash.

The right way to plug out USB Audio device was stop playback function first. Especially when your Windows system is Win 98SE or Win ME, this corrected operation will keep stability of working system. Otherwise, incorrect plug out will cause application program or system crash.

Q2：Why play CD without sound ?

Most general case was digital CD playback function did not open. Because USB audio is a digital signal, it is used 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.

Q3：Why sometimes Win98SE and Win ME can not auto detect USB audio device and switch?

Since Win98SE and Win ME have different driver architecture with Win 2000 and Win XP. When users plug in/out USB audio device too much time or faster, these two OS may not detect the change on device. So, sometimes user got to switch audio device to USB audio device by themself.

While users plug in USB audio device on Win98SE and Win ME system, if system cannot switch audio device to USB, please open “Control Panel”, select “Sounds and Audio Devices”, choice “Audio” page then switch “Default device” to USB Device. 

Note: Do not plug out while application programs were playing media files. Please stop playback before plug out USB audio device.
