Title: LNK4098: defaultlib 'LIBCMT' when using music or soundbuffer and sound. (2.0)
Post by: Jmacman120 on January 04, 2013, 08:14:30 am
I'm trying to play a sound in my program and when I try to use anything from music or soundbuffer I get the error.

int audio()
{
sf::SoundBuffer buff;

if (!buff.loadFromFile("anon.wav"))
{
        //error...
}

sf::Sound anon_m;
anon_m.setBuffer(buff);

anon_m.play();

return 0;
}

This is not an error, just a warning. Your programs works fine, right?

No. Here's the errors I get. http://25.media.tumblr.com/2b8de2f9500d606a86c746b903c88665/tumblr_mg30hpedss1qjlgmjo2_1280.png
And I get errors if I use the Music class as well.

Why did you only mention the warning, and not all the other errors? >:(

Do you link to sfml-audio?

I'm sorry, and I don't know what you're talking about so most likely no. ( I'm new to sfml so I'm still learning.)

The getting started tutorial show how to link to sfml-system. You must do the same for sfml-audio, if you use the audio module.

Okay I fixed that problem but now it says missing libsndfile-1.dll

If a dll is missing you obviously have to copy them to your working directory, so your application can find it. For VS this is by default next to the project file.

Or have the DLLs in a directory which is listed in the PATH environment variable, if you don't want to duplicate them again and again.

The program is working fine now but when I run it, it says "Failed to open audio device" (I have the audio file in the same folder.)

There's a difference... ;)

Do you even have an audio output?
Are your audio drivers up-to-date?

Make sure your application really uses the OpenAL and libsndfile DLLs provided by SFML, not older ones residing in C:/Windows/System32.

I got it to somewhat work now. It say it's playing but I don't hear anything, and yes everything is up to date.

Maybe you could tell how you solved the problem, in case someone finds this thread in the future.
