This may be possible depending if something outside the player software can see the fact that the telephone mute is active. If I remember right, something in /proc indicates this, so a program that monitors that could then fake the IR signal to switch over to aux. Frank, you seem to be the resident expert on faking IR and button presses, do you have a program that lets you send IR commands from the empeg command prompt? With something like that combined with a basic looping shell script, this should be easy to pull off.
