Compact media player with 5.1 support?

Question

Audio

Good day!
I have a Logitech 5.1 Z906 speaker system and needed to play multi-channel audio from it. At the same time, you need as compact a media player as possible or an mp3 player capable of playing independently (from internal storage or from flash media) 4 tracks recorded in one audio file, each track should be played on one column. Can you tell me what options I have and how best to implement it?
