Beep() plays through the PC speaker in Windows 7 only.
That means you are on Windows 7.

Replace beep.sys as mentioned before or create an OpenAL library for this purpose.

Well if your motherboard is hooked up right, and has a speaker (which I'm sure it does), it should play just fine without any external speakers. Just like if you hold down all the arrow keys at once on your keyboard, the beep comes from your motherboard and not the speakers. Mine works just fine and I'm using WinXPsp3 as well.

Check out this source and see if it doesn't help. It uses Beep() and for me plays from the motherboard and not my external speakers. Courtesy of Google, second result in the list.

I assume by “PC Speaker” he means the motherboard speaker.
Apparently he ripped it off or something, and wants sound through his sound card speakers.

My mistake, I assumed the opposite. Anytime anyone I know personally refers to a "PC Speaker" they are talking about the speakers plugged into their sound card.

If this helps any, on this page there are some sources for a MIDI senthesizer and a PlaySound() function that allows playing wav files though the sound card (although it's for Borland, it's still C++). Here's a C++ sound generator for VC2005 that generates sounds from mathematic formulas, it uses DirectSound to play the sound. Also something else that may or may not be of use, if all else fails.

ah so you are sayng to replace my windows xp sp3 beep.sys file with the file beep.sys from windows 7 becose in windows 7 the beep function generates sound directly from the speekers and not from the motherboard speaker,right?
CoMPMStR i dont have a motherboard speaker,i did not known the right term for this thats why i was calling it PC speaker
my english is bad,sorry

Don't apologize... if you ask me, he's got it backwards. I've always known the cheap little speaker on your pc case or motherboard to be the PC speaker. It's the one that makes a beep when you boot.
