Hi, Anyone had this problem with theWDK 7600.16385.0 MSVAD example driver? Playing any wav file (ringin.wav in this test) either by calling PlaySound() or using the Control Panel Sounds Applet results in the file being repeated continuously, effectively hanging the driver. Only happens if XP booted with debug and WinDbg actually connected. No problem if XP booted with debug and WinDbg NOT connected. Installed checked build MSVAD Simple driver on free build XP SP3 using DevCon. Could it be a timout problem? I suspect the repeats come from nt (cannot step this as XP is free build). Is there any way to stop nt (or whatever) repeating the file.
