Multichannel audio support

If hardware in supports multichannel audio, real multichannel audio or virtual multichannel (Dolby Headphone or similar) would be great for example to use, especially with headphones. Would be a great addition to use with videos and live music! Compability to use with android programs would be also bonus. Although this feature is not so called "top priority" feature right now, it could be implemented somehow in future. (This answer is transferred to wiki post in order to prevent getting karma from it. However if you like the idea, please give your vote.)
