seems like I have the same issue on my CX. When I try to force surround, I just hear 2 channels. If its on automatic, it plays 6 tons but they all seem to come out every speaker. Guess the only way around this is to plug the switch directly into the soundbar. I do see it report LPCM within the Vizio app thoughDoes anyone have the Elevate and have working multichannel LPCM via earc? I have a LG C9 (newest firmware that passes LPCM), and it setup correctly (confirmed with c9 earc thread), and i cannot get surround sound to work, the Nintendo "test" only plays 2 channels. plugging directly into the soundbar does get full surround. my ps4 seems to be working via earc but there is no speaker test there to ensure each channel works.
