It''s me again. I''ve just moved my sound code to direct Audio, but I''m a bit confused. Whenever I play a sound or midi, it stops any other sounds playing. They''re on different segments, so I know that''s not the problem. My question is, do I need to use more than one audiopath to play more than 1 wave/midi at the same time, and how many would I need? As many as the amount of sounds I have?

With DirectAudio, you have a main audio path, the default if you want, that plays only music. This is the primary control track that controls timing. Play wave sounds only on secondary audio paths, specifing the DMUS_SECONDARY flag on playback.

The only problem with DirectAudio is that the latency is horrible for playing sound effects. I wrote an entire library around DirectMusic just to find out it can take up to a whole second or two to start playing a sound effect, as the starting time is based off the beat of the primary audio path.

I would suggest using DMusic for MIDI and WAV song files, and keep DirectSound for sound effects.
