Hi,
My driver is being sent null buffers and null values in DoIOOperation.
inStreamObjectID AudioObjectID 33
inOperationID UInt32 1919246692
inIOBufferFrameSize UInt32 96
inIOCycleInfo const AudioServerPlugInIOCycleInfo & 0x0000000102e8f8a0
mIOCycleCounter UInt64 0
mNominalIOBufferFrameSize UInt32 96
mCurrentTime AudioTimeStamp
mSampleTime Float64 0
mHostTime UInt64 0
mRateScalar Float64 0
mWordClockTime UInt64 0
mSMPTETime SMPTETime
mFlags UInt32 0
mReserved UInt32 0
mInputTime AudioTimeStamp
mSampleTime Float64 638896
mHostTime UInt64 0
mRateScalar Float64 0
mWordClockTime UInt64 0
mSMPTETime SMPTETime
mFlags UInt32 1
mReserved UInt32 0
mOutputTime AudioTimeStamp
mSampleTime Float64 0
mHostTime UInt64 0
mRateScalar Float64 0
mWordClockTime UInt64 0
mSMPTETime SMPTETime
mFlags UInt32 0
mReserved UInt32 0
mMasterHostTicksPerFrame Float64 0
mDeviceHostTicksPerFrame Float64 0
ioMainBuffer void * 0x0000000000000000
ioSecondaryBuffer void * 0x0000000000000000
Previous steps seem to correct. What can cause this? What did I miss?
Thanks
Eric
