[janderwald] 39753: - Fix a bug in the audio_test programm which initialized the deviceinfo before another syscall - Complete also an unhandeled irp - Implement IOCTL_CLOSE_WDMAUD - Account the number of times pin can be instantiated in sysaudio and apply changes to SYSAUDIO_CLIENT structure - There is still a bug which prevents closing the audio adapter at the 2nd time

Log:
- Fix a bug in the audio_test programm which initialized the deviceinfo before another
syscall
- Complete also an unhandeled irp
- Implement IOCTL_CLOSE_WDMAUD
- Account the number of times pin can be instantiated in sysaudio and apply changes to
SYSAUDIO_CLIENT structure
- There is still a bug which prevents closing the audio adapter at the 2nd time
