In configuration I can see auxillary out but adjusting the volume does not appear to affect output of MP3-player-headphones connected there. Is this socket different from the headphones socket or not? Also, what's the difference between "speaker" and "system"? thanks, Andrew -- --- To alter your preferences or leave the group, visit //www.freelists.org/list/iyonix-support Other info via //www.freelists.org/webpage/iyonix-support
