I've been trying to run a program I made using OpenAL on a new computer. I have DirectX9.0c installed, but my application crashes when OpenAL tries to open a device. Setting the device to open to "NULL" (supposed to select the default device) or "DirectSound3D" does not work.

This application runs perfectly on my other WinXP PC. Any ideas what could be missing my new Windows box? This needs to be sorted out before I can distribute my program.

In somecase, when NULL selected the default device, it will actually select DirectSound3D (as this is actually the default device).

You could try "DirectSound" or "MMSYSTEM", see if that works.

There was a lot of talk about the naming convensions on the OpenAL mailing list a few months back, but I cant for the life of me find the e-mail (so much for GMail's glorified seraching system!).

Though the fact that it is actually crashing (and not just failing) is a real worry, and leads me to belive that you have maybe got incorrect dll and library versions?

How embarrassing. I hadn't installed the OpenAL distributable on my new PC.

Too many years of good beer and Scotch Whisky.

Thanks again for your help Spree!

in this function...

void killALData()
{
    for (vector<ALuint>::iterator iter = Sources.begin(); iter != Sources.end(); ++iter)
        alDeleteSources (1, iter);

    for (vector<ALuint>::iterator iter = Buffers.begin(); iter != Buffers.end(); ++iter)
        alDeleteBuffers (1, iter);

    Sources.clear();
    Buffers.clear();
}

my compiler (GCC under windows, mingw) says:

cannot convert `__gnu_cxx::__normal_iterator<ALuint*, std::vector<ALuint, std::allocator<ALuint> > >' to `const ALuint*' for argument `2' to `void alDeleteSources(ALsizei, const ALuint*)'

You just need to write iter as &(*iter) in the calls to alDeleteSources and alDeleteBuffers.

Thank you so much... Everything is now O.K.
