Hey! I''m having one of those "I know my mistake is so stupid I will hit myself when I figure it out but for now I don''t know what it is for the life of me" problems. The source code I''m using is below, the problem I isolated with the fopen call due to the fact that the error check at FSOUND_Stream_OpenFile returns with "File not found." I have song1.mp3 plastered everywhere in the directory, in the /debug, I just can''t figure out what''s going wrong. Is there a problem with any other part of the code that is perhaps hindering the loading of the mp3? //********************************************** void SoundMusicInit() { FSOUND_STREAM *stream; FSOUND_SetOutput(FSOUND_OUTPUT_DSOUND); FSOUND_Init(44100, 32, 0); FILE * fp; int length; char * data; fp = fopen("song1.mp3", "rb"); fseek(fp, 0, SEEK_END); length = ftell(fp); fseek(fp, 0, SEEK_SET); data = (char *)malloc(length); fread(data, length, 1, fp); fclose(fp); stream = FSOUND_Stream_OpenFile(data,FSOUND_NORMAL|FSOUND_LOOP_NORMAL|FSOUND_MPEGACCURATE, 0); if (!stream) { MessageBox(g_hWnd, FMOD_ErrorString(FSOUND_GetError()) , "FSOUND_Stream_OpenFile error", MB_OK); FSOUND_Close(); } FSOUND_Stream_SetEndCallback(stream, endcallback, 0); FSOUND_Stream_SetSynchCallback(stream, endcallback, 0); if ((channel = FSOUND_Stream_PlayEx(FSOUND_FREE, stream, NULL, TRUE)) == -1) { MessageBox(g_hWnd, FMOD_ErrorString(FSOUND_GetError()) , "FSOUND_Stream_PlayEX error", MB_OK); FSOUND_Close(); } FSOUND_SetPaused(channel, FALSE); system("pause"); FSOUND_Stream_Close(stream); FSOUND_Close(); } //********************************** Thanks! ~Emre

I''ve never worked with FMOD, but you are calling FSOUND_Stream_OpenFile with the first parameter being "data", when data is a char* to a buffer of the info in song1.mp3. I think you may have over-complicated things for yourself, maybe you should just be calling FSOUND_Stream_OpenFile with the first parameter being "song1.mp3" instead of data. I''m not sure about this since I haven''t worked with FMOD, but since it''s saying "file not found", it''ll want the filename somewhere.
