after reading several posts, I used the Fn and F8 key on my dell laptop to get the tv and computer to "talk to each other" again (had done this last year and it worked fine, but forgot how to do it)..but, now the sound is too low to hear..the computer shows the sound at the highest level, but the sound on the tv will not increase with the remote. I do not remember having any problem with the sound previously. Any ideas?
