I have my (old) pc connected to the HDMI port on a Samsung TV, and all was working great. At one time, after a new preview build install, I lost use of the TV speakers. I waited a week or two, and then a build seemed to bring them back again (I was a happy camper lol). Then, another build dropped the speakers again, and I have not been able to get them to work again. I have uninstalled the speakers and drivers (although control panel shows this as a HDMI jack speaker). I have shopped through the TV menus looking for a hint, but have had no luck. More info available on request, but if anyone can assist, I would love to get the TV speakers working again.
