音频驱动测试

在wince利用微软提供的测试用例测试音频驱动，遇到以下问题：
test：2001 音频播放测试
"ERROR:  expected playtime is too long" (( expected > g_dwAllowance )) [C:\yzqa\private\test\Multimedia\Audio\wave\functional\wavetest\.\test_wavetest.cpp:1616]
Possible Cause:  "Driver notifying the end of playback too late"
test2002 音频播放通知
"ERROR: expected playtime is too long" (( expected > g_dwAllowance )) [C:\yzqa\private\test\Multimedia\Audio\wave\functional\wavetest\.\test_wavetest.cpp:1616]
Possible Cause1:  "Driver notifying the end of playback too late"
"ERROR2: notification not received within one second after expected playtime" (( expected >= 1000 )) [C:\yzqa\private\test\Multimedia\Audio\wave\functional\wavetest\.\test_wavetest.cpp:1618]
Possible Cause2:  "Driver is not signalling notification at all"
test2003 使用扩展功能播放
"ERROR:  expected playtime is too long" (( expected > g_dwAllowance )) [C:\yzqa\private\test\Multimedia\Audio\wave\functional\wavetest\.\test_wavetest.cpp:1616]
      Possible Cause:  "Driver notifying the end of playback too late"
      "ERROR:  notification not received within one second after expected playtime" (( expected >= 1000 )) [C:\yzqa\private\test\Multimedia\Audio\wave\functional\wavetest\.\test_wavetest.cpp:1618]
      Possible Cause:  "Driver is not signalling notification at all"
正在看代码中，有疑问~不知道为什么失败~
