[SOLVED] Bell sound works, but Beep does not produce sound without using headphones

Bell sound works, but Beep does not produce sound without using headphones

Exactly the title. I am trying to use Beep from windows.h in C, however the beep sound (I'm talking about the one similar to the "BIOS beep") does not work as intended unless I have my headphones on. Even the alternative MessageBeep(-1) does not produce any sound without headphones, however BEL or '\a' gives the MessageBox sound as intended.

I do have speakers on without the help of the headphones, since I can play music without them. I did notice a suspecting thing though -- when I press the volume mixer it should play a sound, but that only happens when I am on headphones. No such sound when I'm using the internal speaker.

I also did a sound test of my internal speaker from the Windows Settings; both left and right play the test sound okay.

Anyway, here's a summary snippet.

#include <stdio.h>
#include <windows.h>
int main(void) {
    // Plays nothing on internal, basically equivalent to Sleep(2000).
    // Meanwhile, it does its intended function on headphones.
    Beep(1000, 2000);
    // This produces a message box sound on headphones, 
    // but does not produce anything on the internal speaker.
    MessageBeep(-1);
    // This produces a message box sound, not the BIOS beep sound.
    printf("\a");
    return 0;
}

I appreciate any help, thank you!

Solution

Okay, this is going to be so stupid, I must have touched that part of the Control Panel long before.

I just noticed that even the UAC sound is not working. I also tried a test MessageBox on Visual Basic Script and the sound is also not working. I have concluded and, it turned out, that my system sounds were actually muted when I checked the old Control Panel.

However, the Speaker was on, so \a was actually using the speaker. I do not know what is the case for MessageBeep(-1), though, because it still does not work for me.

So... I guess check your volumes.
