A:AnswerHi, i also bought the Insignia soundbar. I found that two of the soundbars did not accept the optical cord and I could only get sound through using the red/white cable. But one did accept the cable. It was a bit hit or miss. But truthfully, I did seem to nice any difference in sound between the cables and the optical cable.
A:AnswerThis is a digital optical cable for audio. This cable carries digital sound from one component such as a TV to a receiver or DVD player to a receiver for sound.
A:AnswerI don't know about those specific products but this cable really isn't meant to connect to headphones, it should connect to something stationary like from a stereo to speakers.
A:AnswerJust connect an hdmi cable between the cable box and tv. Both audio and video will go to the tv through that cable. If you want audio OUT to go to a stereo, use the optical cable from the tv to the stereo. In other words, the optical port on the tv is an output.
A:AnswerMake sure the polarization (polarity) pin is aligned with the slot on the port. Try turning it 90 degrees each time; it can take a little effort for it to seat properly. if the door is broken off it will not stay in straight and work right.
