I find myself waiting to work on sound until late in the jam. At that point I end up with audio overlap/cutting off, spending time deciding where to place my Audio Sources, etc... For that reason I built this little SoundManager https://github.com/webthingee/UnitySoundManager for Unity. This allows me to have one GameObject that holds a ton of audio. It can add and remove AudioSources as needed so that there is never a conflict. If you're in a pinch, and need a way to quickly manage some sound across your entire game... if it's something you think you could use it out.
