Hi all, I have a TX-42AS520B TV, and I have purchased a SX-HTE80 sound bar. I've connected them via HDMI(to the ARC Out/HDMI in specs as described). Viera Link is on. The audio switches to Home Theatre mode when turned on. The Volume increases on the sound bar with the TV. But there is no audio output from the soundbar. I've searched through the settings for hours to no avail, at a complete loss, about to return the soundbar, any advice welcome. Thanks.
