Hi all,

       I'm using Qt embedded 3.3.6 to develop an application of
recording/playback. The platform I use is S3C2440 plus UDA1380 audio
chip.

       The problem is that I can record the sound from Line-in port
and saved as a raw audio format file. When I play this file in the
qt-based application, the sound seems faster than the original one.
But if I use a simple command-based application to play this file,
then the sound is correct. And I also tested this recording/playback
application on the PC using QT/E X86 compilation edition, the result
is the same.

       Does anybody know what caused this problem?

Many thanks,
Scott
