I have a Samsung TV with optical out and a Panasonic sound bar with both optical and hdmi input. I do have hdmi input on my TV but it will not send sound through to soundbar, the only way I can get sound from TV to soundbar us through optical cable but it does not produce such a good sound as if it was through hdmi which is what sound bar company recommend. Is there a converter which I could plug in from optical out on TV which would convert to hdmi to to into soundbar so I can get better sound please? Thank you Julie
