I recently updated my soundbar to the latest 1006.0 firmware and the HDMI port reverts back to TV SPK almost all the time. The LED display goes between HDMI, MUTE, TV SPK and the image is flickering. I can get the video passthrough with TV SPK but can't get audio. My tv sometimes shows HDMI V Full. Is this a problem with my cable or something else? I had no problem with the cable and the HDMI port before the update.
