Hi all- Im running Win7 off intel NUC, connected to network, have it running 24/7 7 days a week all sleep/hybernatui turned off, last night had sound, everything was ok... it fluxuates but mildly during a show/movie... Then this morning woke up and no sound. says speaker/headphones aren't plugged in. Any thoughts on a solution? Not sure if its a driver issue of Portal issue.. any help would be appreciated!
