Hi Lokesh:
Does your KSPROPERTY_RTAUDIO_BUFFER_WITH_NOTIFICATION call return
successful?
What codec and driver are you running?
Not all the HD Audio drivers are supporting
KSPROPERTY_RTAUDIO_BUFFER_WITH_NOTIFICATION yet. Do might want to check to see
if the driver you are using supports it.
Thanks

KSPROPERTY_RTAUDIO_BUFFER_WITH_NOTIFICATION.
Dear All,
I am trying to get the property KSPROPERTY_RTAUDIO_BUFFER_WITH_NOTIFICATION but
the KSRTAUDIO_BUFFER had the buffer size as 0.I am not sure why the driver is
faling to allocate cyclic buffer.I tried with the two sizes : 1024 and 2048.But
still it returned 0 bytes.Anybody experimented it before.
Initially when i tried with KSPROPERTY_RTAUDIO_BUFFER by giving 2048 bytes,it
allocated 4096 byes sucessfuly.When i switched to
KSPROPERTY_RTAUDIO_BUFFER_WITH_NOTIFICATION it returned 0 bytes.
If anybody have any idea pls let me know.
Thanks
Lokesh
