After re-arranging my set-up, I suddenly have no sound from my external speakers (JBL Creature II). After the first panic, I figured I would try with my MBP. Odly, they work just fine with that. Then i tried with my headphones from my iPhone - no sound at alle. I´ve resetted PR-RAM (twice), and is now stocked - and pissed. Here´s a few screenshots from systemsettings.
