Well, I am new to the world of Android with my new Epic 4G and have been very pleased with a lot of what it can do. However, I really want to know why I can not hear any sound whatsoever simply because the video uses 5.1ch aac instead of 2ch aac. The video part of mp4 plays perfectly, encoded to h.264. I would really like to know if there is any media player able to play these videos correctly without having to resort to any kind of re-encoding (a waste of time when the original encodes should play fine) or having to use special 5.1ch headphones (bulky and not practical to keep on hand all the time). Also, does anyone know if this might be corrected with Froyo 2.2? And last, all my videos that have 2ch audio play as they should, sound and all. Same codec settings were used.
