Solution 1

The problem is with your filename. The compiler is using the single \ as the start of escape sequences. You know, just like you use \n as the escape sequence for a newline.

The solution is to either

Make them all \\ instead of \
Make them all / instead of \

I used
PlaySoundW(L"C://Users//Chaiein/Downloads/oscilloscope_src//sound1.wav",NULL, SND_FILENAME); still it doesn't work

Nope. It wouldn't. Use this:
PlaySoundW(L"C:/Users/Chaiein/Downloads/oscilloscope_src/sound1.wav",NULL, SND_FILENAME);
PlaySoundW(L"C:\\Users\\Chaiein\\Downloads\\oscilloscope_src\\sound1.wav",NULL, SND_FILENAME);

I.e - you should use either / or \\
Anything else is junk. :)

I used PlaySound("sound1.wav",NULL,SND_FILENAME); It worked but with my project which was developed in mfc but not in win32 application. Should I use different command for playing sound in win32.

How does it "not work"? It does not compile? It does not get linked? It does not play the sound? It crashes?

Should use double-backslash in the file path when giving file name through code eg: L"C:\\Voice\\wave\\sample.wav"

I had made mistake with the wav file because of its name sound1.wav.wav I created new sound1 file problem solved..


PlaySoundW(L"C:\\Users\\Chaiein\\Downloads\\oscilloscope_src - Copy\\sound1.wav",NULL, SND_FILENAME);

Thank you all of you for solution:)
