Nullsoft DirectSound Output v2.47 Error code: 88780078

Hi,
Since I start using Windows 7 my problems with sound started too. I have sound drivers SoundMax installed.
Beside it my sound don’t work normal.
When I run winamp to play music I got an error message.
I don't know what should I do? Any suggestion will help.
Thank you
Kenneth
