There are drivers and software for mp3-decoder hard/firm-ware (eg ipodlinux.org ) - shared/locked memory is an issue on embedded devices, and USB makes this even worse..! I think the cheapest solution is to just /connect/ the mp3-de/encoder/player output to a general purpose dsp & mixer chipset and have them be two separate [usb] devices.. 2c, robin _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo.cgi/linux-audio-user
