麻烦斑竹看看

pdfer

我装了hero3，有的时候能运行有的时候就不行，只要一运行就出现
Couldn't open audio: Couldn't open audio device or ESD connection
X Error of failed request: BadMatch (invalid parameter attributes)
Major opcode of failed request: 42 (X_SetInputFocus)
Serial number of failed request: 70
Current serial number in output stream: 71
这时就黑屏了，并且所有用到声卡的程序都用不了，重启后就又正常了：(
这是怎么回事呢？谢谢
