Hi everyone, I've got an up to date Lion rocking my MBP, but lately I have been having problems when I connect my external audio system. The output is mono only for some reason.. it clearly is a bug because if I restart the system I get stereo again.. I tried fiddling in the system preferences pane with no luck so far. Any idea how this behavior can be changed? (restarting the MBP everytime I come home is a hassle.. plus it used to work flawlessly) Thanks in advance! Edit: I am not using an optical connection to my system (should that matter).. copper only.
