I suppose the "correct" way would be to use the mysterious
osso-media-server for audio playback, but I don't know of any
documentation on this.

Therefore, the easier way is to use libSDL (which is an integral
library on the 770 anyway) to play sounds. libao with esd backend
works as well but would add an additional unnecessary dependency to
your application and provides no means for volume control.
