Greetings. I set up my Roku streaming stick + by plugging it into HDMI port on my TV that connects to my Sony stereo system but I am unable to hear any sound. TV to stereo connection uses the old component cable (blue, green, red) and it works fine without Roku. Once I plug Roku into the HDMI port I can only use my TVs speakers. Any steps I need to do in my Roku settings ? I tried setting audio mode to Stereo and HDMI to PCM-Stereo or Dolby Digital, DTS as recommended by Roku but no luck. Any ideas ?
