I have an Asus Laptop with an HDMI output, a Panasonic Smart TV with HDMI 1, HDMI 2 (ARC) AND HDMI 3 and a Marantz SR5004 surround receiver. I've connected the laptop to HDMI 1 of the TV and from the HDMI 2 (ARC) of the TV to the HDMI OUT (ARC) of the receiver. My problem is this; when I play movies or music from my laptop (encoded DTS Surround) I only get stereo output. I have 7.1 surround capabilities. Any ideas?
