i have a player almost ready for this. It works with libmad, so decoding mp3s on n770 takes 10-15% processor, and uses alsa for the output - so it should work with a2dp. It's done in C and it's very fast, takes max 20% cpu, but has some skipping whenever another app takes too much cpu. I'm working on it, problem is the alsa buffer is very small - 4KB, so I need a lot of pooling to keep it full. It will have visualizations and EQ support later, now i try to make the playlist usable, and lower the cpu as much as possible. I could post the n770 mplayer with alsa and mp3 support if there is demand, but it's not very usefull with Kagu just yet on n770. cheers
