Did you «Buy a new cable with a 3 pin connector to connect to the original cable to the ML-PL-module and solder the new cable to the two soldering points of the optical connector on the solder side of the Via motherboard» ?
My system works fine and I hope I don't have to buy a new motherboard anytime soon and even though I find the thought of soldering anything on a motherboard quite daunting, I'm thinking perhaps I should buy this cable now before it becomes difficult to find?
Best,
