Audio alerts?

Is there a way to play an audio clip / alert in an addon? Or is it best to just input a <call#> to the game?

There's a windower.play_sound function, but I'm not entirely sure how it works. It may only be able to play .wav files.

windower.play_sound just does a few checks to make sure the file exists and then calls the Win32 PlaySound function, which I don't believes supports anything other than WAV files with a linear PCM codec*.

* Yes, you can have WAV files with other codecs, even MP3. WAV is just a container format; actually they're RIFF files.

Thanks!
