My very old Denon receiver has never been able to handle HDCP, so I have never used the HDMI switcher built into the receiver and up until now it hasn't been a problem. I have always taken video sources directly into the Television and then whatever source I was using I would either take the coax audio or optical audio into my Denon recover. This has served me well for the past 14 years. My receiver only acted as a audio switcher, not ideal, but i have made it work for years. Now I find myself in a pickle, because I want to replace my ROKU 4 with a new ROKU box and none of the new ROKU boxes have an optical audio output. It is strictly HDMI. So I was wondering if any of the HDMI audio extractors like this: https://www.amazon.com/J-Tech-Digital-Premium-Extractor-Converter/dp/B00BIQER0E/ref=sr_1_1?ie=UTF8&qid=1517583937&sr=8-1&keywords=hdmi+audio+extractor Are worth buying. I know i can replace my receiver with a newer unit, but that would require tricking the wife into buying it and I don't want to fight that battle today. I emailed Roku and they don't recommend anything. So I am taking the pulse of this community to see if anyone out there has had personal experience with these devices.
