Error in WaveInPrepareHeader API

[temp123]

I am trying to make application for VOIP call on PPC using event base polling for WaveIn ans WaveOut. It works fine upto 50-60 call and after that WaveIn/WaveOutPrepareHeader APi throws MMSYSERR_NOMEM error and device needs to be reset for further call.

I follow the following sequence,

WaveInOpen
WaveInPrepareHeader
WaveInAddBuffer
WaveInStart


WaveInStop
WaveInReset
WaveInUnPrepareHeader
WaveInClose


Any API doesn't throws any error during successfull call but after 50-60 call , MMSYSERR_NOMEM error occurs for both WaveIn/WaveOutPrepareHeader.

I cross check for memory leak in program but it is not there.

Any clue for same would be appriciated.

You need to try this driver-tool:

And see if you get the correct data at audio driver level.
eg: you call WaveInPrepareHeader in your program, and see if you get the call at driver level using this tool, and if it has the same parameters, etc.
