i have Verizon Fios and my tv is RCA but it is old, the volume seems to not work at all. yesterday it was working fine. the only reason i know its the tv is because when i played wii it didnt have sound on the tv. then when we watched tv today it had subtitles and it wasnt muted but im pretty sure it is the verizon fios messing it up since the volume does work.now. its pretty confusing, so if you need me to explain it another way or tell you something more, ust ask because i think that was written pretty illiterately, haha. thanks.
