I'm trying to fade out the background music using OALSimpleAudio but I can't figure out how to do it. When I used SimpleAudioEngine I called:
[CDXPropertyModifierAction fadeBackgroundMusic:1 finalVolume:0 curveType:kIT_Linear shouldStop:NO];
and everything worked fine, but now it doesn't work. I've found that OALAudioTrack has a fade out function but I don't know how to call OALAudioTrack from a OALSimpleAudio instance.
Is there any way to fade out using OALSimpleAudio?
