Solution 1

Try this line of code.

C++

WAVEINCAPS wOC = {0};

What does waveInGetDevCaps() return?

i checked the result of waveInGetDevCaps() and initialized the wOC var

the return value is MMSYSERR_NOERROR.

int nwaveInDevs = waveInGetNumDevs();
	
	if ( nwaveInDevs ){

		WAVEINCAPS wOC = {0};

		if (MMSYSERR_NOERROR  == waveInGetDevCaps( 0,&wOC,sizeof(WAVEINCAPS)))
			AfxMessageBox("DONE it!!");

	}

but stll with the debug i get

wChannels = 65535

story is the same for waveOut....
