Crash in LPDIRECTSOUNDCAPTUREBUFFER->Release() after System sleep on Vista
Anthony Wieser
Assume:
LPDIRECTSOUNDCAPTURE m_pDSCapture;
LPDIRECTSOUNDCAPTUREBUFFER m_pDSBCapture;
LPDIRECTSOUNDNOTIFY m_pDSNotify;
When my thread exits, I call
m_pDSBCapture->Stop();
then
SAFE_RELEASE( m_pDSNotify );
SAFE_RELEASE( m_pDSBCapture );
SAFE_RELEASE( m_pDSCapture );
but the call to
SAFE_RELEASE( m_pDSBCapture );
crashes with the following stack trace below it.

This crash only seems to happen though when I put my system to sleep. when
it wakes up, it appears to continue to capture correctly, but fails when I
try to clean up.
Here's the output from dxdiag about my sound card:

Is there any other information in the debug output? It appears to be
something with the heap memory and it should tell you if the heap is
corrupt or that memory was modified after it was freed, etc.

Just the access violation address.
Here's the contents of the output window:
First-chance exception at 0x770e59c3 (ntdll.dll) in _demo.exe: 0xC0000005:

So far it looks like there was an extra Release called on entry to sleep.
You can catch sleep notification and shut down Direct Sound at that time.
