Q3 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. So, when user plug out USB audio device windows
system can not delivering 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 was Win98SE or WinME, this corrected
operation will keep stability of working system. Otherwise, uncorrected plug out
will cause application program or system crash.
