 |

Regardless of how much coding must be done, is it possible to change the speaker volume with C++? Drivers, etc.?
If so, example please?

I have XP, so.. yeah. 
But using noz3001's reply, here's the test code I'm using:
| Code: | #include <windows.h>
int main(){
for(;;){
while(!GetAsyncKeyState(VK_F12))
Sleep(100);
while(GetAsyncKeyState(VK_F12))
Sleep(10);
waveOutSetVolume(0, 0);
}
} |
I'm getting this error:
| Code: | | main.obj : error LNK2019: unresolved external symbol __imp__waveOutSetVolume@8 referenced in function _main |
Help?

Thanks, got it working. Now I want to play a sound. I'm using..
| Code: | | PlaySound("beat.wav", 0, SND_FILENAME | SND_LOOP); |
It keeps returning 0 and nothing happens. "beat.wav" exists in the same directory as my program. Help?

Try adding the full path and see if it works.

How are you running your program.
Because if you run via F5 (Run&Debug) I believe it uses the directory where all the source files are located. Full path would work or put the file in both the Debug/Release folder and source folder to see if it works then.

| I've changed my settings to build the program on my desktop. I'm building it then running it manually. My WAV file is also on my desktop. I read somewhere that I need to import (or something like that) winmm.lib. Help? I already have #pragma comment(lib, "winmm.lib") at the top, and typed in "winmm.lib" in Project Properties >> Linker >> Input >> Additional Dependencies. PlaySound still returning 0. Any ideas?

| Hmm.. interesting. Now it's returning 1, but nothing's playing. My speaker's on, I've also set the volume back at 0xFFFF.

| I think it's ultimately a problem with my computer and sound.. I can never listen to the sound on YouTube either. Ever since a couple years ago.. something happened.
