I just recently bought a Phillips Smart TV, model 39PFL2908. The installation went fine and was able to wirelessly hook up the pc laptop to the tv using Wirelessconnect. The first time I tried watching something on the tv from transmitting a tv show from the laptop, it worked well. The pc sound was muted instantly the moment it connected to the tv. However, a few days passed, and I tried watching a tv show again...but this time sound was heard from both my tv and my laptop. Couldn't figure out why, so I uninstalled the wirelessconnect software, downloaded it again... and everything worked fine - the pc sound was muted. Now, I try AGAIN today, and the SAME problem of the pc sound NOT muting. What is going on here??? Someone please help!!!
