I just bought a 40" Samsung TV model # UN40H5500AF thought I could hooki it up to my Philips DVD/Home Theater system HTS3450. Couldn't do that because the tv doesn't have the same audio in/out as the system It has the HDMI or Digital Audio out but my system has the older coax/rca audio plugs. I bought the monoprice 5557 HDMI box but no luck on getting anything to work with the box. I can use the dvd and hear sound out of the home theater with the dvd but really wanted to use it for the tv as well. I do not have a cable box or such because I don't have cable I just use Hulu Netflix excetera Is there any way to get the sound to work for just the regular shows? I hate to buy a sound system for the tv when the other one works for the dvds, its hardly used and in good shape. Don't want to buy new dvd player sound etc just for this!!
