I have been trying to get my Roku to play audio through my surround sound system attached to my Samsung blu-ray player. I have both the bluray and the Roku attached through HDMI. The problem is when I set the Roku to surround sound it wont play any sound and I get an error message saying an incompatible audio signal has been received. I can hear the audio when I set the Rokue to stero, but the sound plays through my TV speakers which suck. Is there any way to get the Roku to play though my surround sound system?
