hi,everybody
I want to create a duplex buffer.But DirectSoundFullDuplexCreate
often fail ! it is exhuasting me now! I appreciate your help.
This is My source code:
What it the error code returned? Error codes are you friend, look it up
with DXErr.exe.
Not that it should make a difference, but I always use Instance values of
GUID_DSCFX_MS_AEC, GUID_DSCFX_MS_NS instead of the system default.
Remove the DSBCAPS_CTRLVOLUME flag, I don't believe this is supported.
It's not necessary to pass the DSBCAPS_CTRLPOSITIONNOTIFY flag, you can
still set notifications.
Use 1 channel, 16000Hz @ 16 bit. This system will use that rate
internally.
