I have an old Fujitsu plasmatv p42vha40. Comcast has asked me to upgrade my cable box to the new hdmi cable box. I connect the cable box to the TV using HDMI wire. I got the video to work but cannot get the sound to work.what am I doing wrong? I checked the forum and I already checked the audio output...it only gave me option of stereo or surround. Can you help. Do I need a new hdmi wire? Is my tv too old?
