Just got a Beam and am frustrated. I have it hooked up to my TV via ARC, but when I tried to play Jurassic Park on Netflix, no sound came through. On some channels, movies, etc the sound works fine. I went to my Vizio P75 sound settings, and there is a "digital audio out" menu. My choices are Auto, Bitstream, Dolby D, and Pcm. The only selection that will send Jurassic Park through my Sonos is PCM. That does me no good, because I have surround sound.
What do I do? And also, why wouldn't "auto" automatically select a format that plays correctly?
