MCI Command strings

[Anteater]

Hi. I'm using Irrlicht for graphics, and MCI strings for sound (they support midi), And I have run into a problem. The only time I can get music/sound to play is at the very start of the console. Any ideas?

Code:

Maybe DirextX gets in the way? MCI seems to be built on top of DirectX, maybe it conflicts somehow?
If you move your mci play command to the line just after the createdevice call, does it work?

Maybe the mci play command does not stop until you explicitly send a stop command?

system("pause") just waits for a keypress, but I assume you know that.

It's difficult to see what's wrong with your sound code if you don't post any (other than that initial mci command), by the way.

Although I don't have an answer to your problem. I thought I might suggest that you take a look at FMOD http://www.fmod.org/ which has the ability to play MIDI files.

It looks like you are loading the sound before the device. That will cause you problems. I, like the answer above, would suggest you load your app before you load your sound. I load my sound files last.
