如何让PC主机上的喇叭发音?

[hboy]

除用MessageBeep还有其它的方式吗,如用汇编,可提供源程序吗?我对汇编可不懂,
MessageBeep也太烂了,在98下只能发一种音,并且还不怎么响.

// 通过PC喇叭发出声音
UINT Sound(LPVOID pParam)
{
int FreqTable[100];
int DelayTable[100];

for(int i=0;i<10;i+=100)
{
FreqTable[i]=50*i+500;
DelayTable[i]=100;
}

int *nFreqTableLength = (int *)pParam;
int Freq;
for(i=0;i<*nFreqTableLength;i++)
{
Freq=FreqTable[i];
if(Freq<37||Freq>32767)
{
_outp(0x61,_inp(0x61)&0xFC);//NoSound()
continue;
}
Freq=1193181/Freq;
_outp(0x61,_inp(0x61)|3);
_outp(0x43,0xB6);
_outp(0x42,Freq&0x00ff);
_outp(0x42,(Freq&0xff00)>>8);
Sleep(DelayTable[i]);
_outp(0x61,_inp(0x61)&0xFC);//NoSound()
}
_outp(0x61,_inp(0x61)&0xFC);//NoSound()
return TRUE;
}

void NoSound()
{
_outp(0x61,_inp(0x61)&0xFC);
}
