Cablesson HDElity HDMI 7.1ch Audio Extractor & Mixer - HDCP, HDMI Deep Colour, 3D Support with EDID - HDMI 2.0 Multi-Channel Audio Extracter Converter for Blu-ray DVD Player SKY HD Box PS3

I used this equipment to hook up my laptop with my av receiver. I only had an hdmi out from my laptop and my av receiver cannot process sound from hdmi cable. Therefore I needed to separate the digital sound from hdmi and send it to my av receiver via a coaxial or optical cable. I used a coaxial cable but the equipment has optical cable out as well. I have 8 meters of cabling (high quality) between my laptop and av receiver. It works...Sound and vision is awesome.
