Bose Soundbar 700 surround sound issue
I posted a similar question on Bose's site, but I'm hoping someone here might have actually encountered this issue, and I'm suspect of their actual technical expertise.
Have the soundbar connected to an LG C7 via HDMI ARC, and just bought the rear surround speakers a week ago. Doing some surround testing using either Youtube videos or a calibration DVD, I find that the rears seem to mirror the "fronts." In other words, when the test signal is sent to the right "front" speaker, the sound comes out of that speaker as well as the right surround speaker. Likewise when the signal is sent to the right rear speaker, I hear it from that speaker and the front. It sounds like it's really only a 3 channel system. When running the Bose AdaptIQ app, the signal sent to each speaker is in fact discrete, there is none of this overlap.
On the TV sound out, the only option I can toggle is to change the signal out between PCM and "Auto"(whatever that is). Changing this has no impact on the issue.
