    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.

    What applications do you typically use when this behaviour occurs?

    Well I have tested if this was an application dependent issue, but I have the problem with any app that outputs sound (iTunes, safari/chrome (e.g. youtube), vlc, ..)

    Maybe you're talking about which application I usually run? Then there's a lot of them.. parallels, skype, adium, some X11 apps, xcode, some specific development tools (CS student here :)),.. I usually end up with everything opened since i don't restart the MPB unless updates have been released.

    Do you have anything specific in mind?

    Thanks!
