Would it still work to plug everything into the soundbar and then connect to TV with HDMI even if ARC is not supported? Or do I need to plug evertthing into the soundbar and then have an HDMI *and* optical audiot cable going to/from the TV? I ask because the initial post in this thread indicated that the TV would not pass along the Dolby audio to the soundbar. My TV does have a Dolby Digital decoder so I don't know if the same rules apply or not. Not having all the various cables needed to test the various setups, I'm a little confused about the best way to set it up and can't current just test each method to see what works and what doesn't.
Thanks for any help.
Hmmm, you quoted my post from awhile back that should have answered your questions, but let me try again.

If you leave your source devices connected to the TV, then yes, you need to connect optical from TV to soundbar to get audio since the TV does not support ARC. (Reread my post where I explain ARC).
A better solution is to connect your two source devices via HDMI to the soundbar and then connect the soundbar via HDMI to your TV. The soundbar processes the audio directly and outputs video only over the HDMI connection to the TV.
All HDTVs that have an ATSC tuner can decode and output DD, but they output DD ONLY from the tuner, not from devices connected to the TV.
