The driver stops working sometimes but can be recovered.

I am using the latest binary 3552 version on windows 8.1 x64 version. I used the Creative Audigy 5 card.
It works normally most of the times, but sometimes, it stops working with silence or a simple sound like “di…”, when I click the windows sound bar:

to let windows make some sound, the “di…” sound changes its volume or pitch, or changed to silence.
After several times of clicking, the driver recovers and everything works again.
Usually the driver stops working is because the system makes a sound or the music player changes a song.
So I guess each time a new sound is put into a channel, it has a chance to stop the driver from working.
