I write start of program to learn english (class and two files) and I want to play sound so I play it as wav files but I can't load it the compiler throw error “unsupported block alignment” I search on google I didn't found an answer can any person help….!

I load it with Mix_LoadWAV and I get error “unsupported block alignment”

this is my main class:

class Lrecord

{

public:

Lrecord();

~Lrecord();

void init_recocall(int recordingDeviceId, int playbackDeviceId, char* chc, char* chd, int y);

//Focuses on window

void focus();

void handleEvent(SDL_Event& ev);

//Window dimensions

int getWidth();

int getHeight();
