I support IP softphone which uses winmmAPI. Very intermittemtly our application reports crash in wdmaud.drv module.
Problem signature:
Problem Event Name: APPCRASH
Application Name: i2050.exe
Application Version: 4.0.4.132
Application Timestamp: 52fdc18c
Fault Module Name: wdmaud.drv
Fault Module Version: 6.1.7601.17514
Fault Module Timestamp: 4ce7ba26
Exception Code: c0000005
Exception Offset: 00004dc9
OS Version: 6.1.7601.2.1.0.256.4
Locale ID: 1033
Additional Information 1: 0a9e
Additional Information 2: 0a9e372d3b4ad19135b953a78882e789
Additional Information 3: 0a9e
Additional Information 4: 0a9e372d3b4ad19135b953a78882e789
Collected dumps show that in most cases the crash occurs in
wdmaud.drv!CWorker::_DoRecurringJobs() + 0x5e bytes (or _DoRecurringJobs() + 0x63 bytes)
wdmaud.drv!CWorker::_ThreadProc() + 0x265 bytes
wdmaud.drv!CWorker::_StaticThreadProc() + 0x2e bytes
Since the issue occurs very intermittently it is unclear which actions from our application side can cause the crash. Sometimes it happens when the phone starts to work with audio, sometimes when finishes.
The issue occurs on Win 7 64 bit Service Pack 1.
I surfed the internet thoroughly but didn’t find any clue so would appreciate any ideas.
