Okaay! finally figured it out after reading all of this and being stuck for like an hour, read soo much stuff an none of it worked but I ended up figuring it out myself! obvi I have the same problem as you. what you gotta do is right click the sound icon, and click playback devices. once that pops up select speakers and click properties on the bottom right. once another window pops up click properties again under 'controller information'. after the window pops up click change settings on the bottom that has the little administrator logo. that should reload that current window 'cept change settings shouldnt be there. now click the driver tab and click roll-back driver because you most likely already have the up to date one, this brought me back to 2010. then click update driver and viola! that let me open up the sound bar again, thank friggin god!
