I have an audio problem with my new 3416 from RCN in Boston. I have an all HDMI connection with the new Sony strdg820 and a Onkyo 6 speaker Surround system. First, the video out of this box is great and it functions smoothly. However I can only get 2ch stereo out of the 3416, no matter how I reconfigure. I have spent hours with tech support from both RCN (Not Helpful) and Sony (Very Helpful) but still only 2ch. Can anyone make a suggestion or help!! Thanks. Lots of great info on this forum.
