Napisal (ili daje sodral s helpa) programmku vivoda buffera na sound cartu. Inizializiruyu cartu sleduyuschim obrazom:



bool waveStartPlay(memBlock (*ProcessPlay)(void), AnsiString& errMes)
{
DWORD err;
MIXERLINE mixerLine;
unsigned long n, numSrc;
int i=0;


//
ProcessPlaySound = NULL; // Clear processing
if(InPlay == TRUE) // Go away if already playing
{
errMes="Already record. Press stop before!";
return false;
}

if(ProcessPlay == NULL)
{
errMes="No process function defined (pointer==0)";
return false;
}
ProcessPlaySound = ProcessPlay;
InRecord = FALSE;

WaveFormat.wFormatTag = WAVE_FORMAT_PCM;
WaveFormat.nChannels = 1;
WaveFormat.nSamplesPerSec = 8000;
WaveFormat.wBitsPerSample = 2;
WaveFormat.nBlockAlign = waveFormat.nChannels * (waveFormat.wBitsPerSample/8);
WaveFormat.nAvgBytesPerSec = waveFormat.nSamplesPerSec * waveFormat.nBlockAlign;
WaveFormat.cbSize = 0;




/* Open the default WAVE Out Device, specifying my callback */
err = waveOutOpen(&HWaveOut, WAVE_MAPPER, &WaveFormat, (DWORD_PTR)WaveOutProc, 0, CALLBACK_FUNCTION);
switch(err)
{
case MMSYSERR_INVALHANDLE: errMes = "Error open. "+IntToStr(err) + " MMSYSERR_INVALHANDLE"; return false;
case MMSYSERR_BADDEVICEID: errMes = "Error open. "+IntToStr(err) + " MMSYSERR_BADDEVICEID"; return false;
case MMSYSERR_NODRIVER: errMes = "Error open. "+IntToStr(err) + " MMSYSERR_NODRIVER"; return false;
case MMSYSERR_NOMEM: errMes = "Error open. "+IntToStr(err) + " MMSYSERR_NOMEM"; return false;
case WAVERR_BADFORMAT: errMes = "Error open. "+IntToStr(err) + " WAVERR_BADFORMAT"; return false;
}


Vsegda poluchayu oshibku WAVERR_BADFORMAT. Pochemu? Vse vrode OK.
Napisal esche programulinu dlya zapisi zvuka ispol'zuya waveInOpen...
Esli zapuskayu snachala zapis' zvuka, a potom proigrivanie, to vse OK. Podskajite, gde mojet bit' problema, a to ya uje ustal hodit' po krugu.

I esche, kto-nit' nahodil rabochie primeri s ispol'zovaniem waveOutOpen. Esli da, kin'te link pls

S uvajeniem.
